NCERT Solutions for Moving Charges and Magnetism Class 12

Class 12 Physics typically covers the topic of moving charges and magnetism, which is an essential part of electromagnetism. Here's a brief overview of the key concepts:

1. Magnetic Field (B):

A magnetic field is a region around a magnet or a moving electric charge where magnetic forces are experienced.

The SI unit of magnetic field is the tesla (T).

2. Magnetic Force on a Moving Charge:

When a charged particle moves through a magnetic field, it experiences a magnetic force perpendicular to both its velocity and the magnetic field direction.

The magnitude of the force is given by the formula: F = qvBsinθ, where q is the charge of the particle, v is its velocity, B is the magnetic field strength, and θ is the angle between v and B.

3. Lorentz Force:

The total force experienced by a charged particle moving in an electric field (E) and a magnetic field (B) simultaneously is called the Lorentz force.

The formula for the Lorentz force is given by: F = q(E + v x B), where x represents the cross product.

4. Magnetic Field due to a Current-Carrying Conductor:

Ampere's law states that the magnetic field produced by a current-carrying conductor is directly proportional to the current and inversely proportional to the distance from the conductor.

The direction of the magnetic field can be determined using the right-hand rule.

5. Magnetic Force between Two Parallel Current-Carrying Conductors:

When two parallel current-carrying conductors are placed close to each other, they experience a magnetic force due to the interaction of their magnetic fields.

6. Magnetic Field due to a Circular Loop:

A circular loop carrying a current produces a magnetic field similar to that of a bar magnet. The field is stronger inside the loop and weaker outside.

7. Torque on a Current Loop in a Magnetic Field:

When a current-carrying loop is placed in a magnetic field, it experiences a torque, which tends to align the loop with the magnetic field.

These are some of the fundamental concepts covered in the topic of moving charges and magnetism in Class 12 Physics. Understanding these concepts is crucial for various applications, including the functioning of electric motors, generators, transformers, and many more.

NDA Preparation Strategy from Class 11 – Step-by-Step Plan

The National Defence Academy (NDA) is one of the most prestigious defense institutions in India. It also attracts young aspirants who aspire to serve the nation. Even from Class 11, many students begin their preparation to acquire a foundation strong enough to help them.

But, while they mean well, many candidates make mistakes that commonly undermine their performance in the NDA exam. If you want to know how to prepare for NDA from class 11 this blog will give you pointers on what not to do and how to prepare better.

1. Ignoring the Basics of Mathematics and General Ability

Mathematics and General Ability are courses that many of our students pay attention to only advanced topics without paying attention to basic concepts. Such a mistake makes it difficult to solve complex questions during the NDA exam. The mathematics section depends primarily on strong fundamentals, whereas GAT is concerned with English, general knowledge, and science.

Solution:

Strengthen the basic skills if you want to learn to prepare for NDA from class 11. Regularly revise Class 11 Mathematics topics like Algebra, Trigonometry, and Calculus. Various ways, such as reading newspapers, news channels, etc., are the various ways to improve English and general knowledge.

2. Not Following a Proper Study Plan

There are many students who don’t have a structured plan, and they prepare for NDA, and both subjects are not covered in the complete syllabus. They are wasting time and struggling to manage their studies at school and studies in NDA without a proper study schedule.

Solution:

Outline a well-structured study plan that includes all the NDA subjects. Use enough time for mathematics, English, and general knowledge. Set daily goals and weekly goals to see the progress. Class 11 academics and follow a routine and NDA preparation: This discipline prepares you for thorough preparation and lessens last-minute stress.

3. Ignoring NCERT Books

Coaching material is relied upon by some aspirants, but few people give importance to NCERT books. This is a big mistake because nobody can compare more than the NCERT books for NDA preparation. The Mathematics and Science sections are very much based on the NCERT content.

Solution:

NCERT books for Class 9-12 should be commenced with the start of preparation for NDA. After this, start having a look at reference books and practice papers. This way represents thorough knowledge and better problem-solving.

4. Not Practicing Previous Year Papers and Mock Tests

In many ways, the reason why students don’t solve NDA previous year question papers and mock tests is that they fail to solve them and end up with poor performances in the exam. They battle with time management and do not have patterns without regular practice.

Solution:

Solve at least 10 to 15 years’ worth of previous year NDA papers. To improve accuracy and speed, attempt mock tests weekly. Focus on the weak areas that need working on and consistently so. Mock tests help aspirants to get more confident and to prepare for real exam conditions.

5. Underestimating the SSB Interview

Services Selection Board (SSB) interview preparation is neglected by most NDA aspirants, who fix their whole preparations for the written exam held by UPSC. The leadership, personality, and decision-making skills administered by means of this interview are very important in the selection stage.

Solution:

Start SSB interview preparation early. They build communication skills through public speaking and debates. It also involves reading about current affairs and defence-related matters. Maintain physical fitness as SSB has physical fitness assessments. In order to increase confidence and prepare oneself for interviews, group discussions, and psychological tests are practiced.

6. Neglecting Physical Fitness

Among NDA aspirants, there is not much focus on the physical fitness to which applicants need to give importance. Failing the medical test means disqualification, and the NDA demands very high endurance, strength, and medical fitness.

Solution:

Run, do push-ups, and do more endurance-based exercise daily. Ensure proper sleep and continue a healthy diet. Junk food and too much screen time are to be avoided. Go out and engage in some outdoor sports to improve stamina and overall fitness.

7. Lack of Consistency and Motivation

Conclusion

If you begin how to prepare for NDA from class 11, you’ll have ample time to create a firm footing. Although it is necessary to avoid making common mistakes such as leaving the basics, neglecting NCERT books, or underestimating the SSB interview.

Consistency, a structured study plan, and time spent on academics and physical fitness can help you boost your chances of success. The key to mastering the exam pattern and using time well is regular practice through mock tests and previous year papers.

Physics Notes Chapter 3 Current Electricity

Here are important notes for Class 12 students on CBSE Physics Chapter 3 Current Electricity. This chapter explains the basics of electric current which is the flow of electric charge through a conductor.

It also covers current carriers like electrons in metals and ions in solutions that move to create the current. The chapter talks about drift velocity which is the average speed of these carriers when an electric field is applied. 

You’ll also learn about Ohm's Law, Kirchhoff’s Rules and how resistors work in circuits. These notes are helpful for understanding how electricity flows in circuits.

Electric Current

Electric current is the flow of electric charge through a conductor. In most cases, this charge is carried by electrons moving through a wire or other conductive material. The amount of electric charge that flows through a conductor per unit time is defined as the current which is represented by the symbol II I.

It is important to note that electric current is considered a scalar quantity . Even though it has a direction (from positive to negative terminal), it is not a vector because it does not follow the rules of vector addition.

Current Carriers

Current carriers are the charged particles that move through a conductor to create an electric current. Depending on the type of material (solid, liquid, or gas), the nature of these current carriers can vary:

In Solids :

The most common current carriers in solids, especially metals, are electrons . In metallic conductors, free electrons move through the lattice of positive ions when an electric field is applied, resulting in a current.

Metals have a large number of free electrons that are not bound to any particular atom, allowing them to move easily through the material.

In Liquids :

In liquids, the current is carried by ions . When an electric field is applied, positive ions (cations) move towards the negative electrode (cathode), and negative ions (anions) move towards the positive electrode (anode).

This movement of ions constitutes an electric current. An example of this is the conduction of electricity in saltwater or any other electrolyte solution.

In Gases :

In gases, current carriers are a mix of electrons and ions . Normally, gases are poor conductors, but under certain conditions (like high voltage), they can become ionized.

In ionized gases, free electrons and ions move under the influence of an electric field, resulting in a current. This phenomenon is commonly seen in neon signs or lightning.

Drift Velocity

Drift velocity is the average velocity that a charged particle, such as an electron, attains due to an electric field applied across a conductor. It represents the net motion of charge carriers in a conductor when an electric field is applied. 

Drift velocity is different from the random thermal velocity of the particles, which is much higher.

Ohm’s Law

Ohm’s Law is a fundamental principle in electrical engineering and physics that relates the voltage, current, and resistance in an electrical circuit. It states that the current through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant.

Drawbacks of Ohm’s Law

While Ohm's Law is widely applicable, it has certain limitations and does not apply to all materials and situations:

Non-Linear V-I Relationship : Ohm's Law assumes a linear relationship between voltage and current. If the relationship between V and I is non-linear, Ohm's Law does not apply. This nonlinearity can occur in devices like diodes and transistors, where the resistance changes with the voltage or current.

Dependence on Voltage Sign : In some materials and devices, the relationship between current and voltage can depend on the sign of the voltage. For example, certain semiconductor devices may exhibit different behaviors when the polarity of the applied voltage changes, leading to a non-Ohmic behavior.

Non-Unique Relation : Ohm's Law implies a unique resistance for a given conductor. However, in practical scenarios, the resistance can vary with factors like temperature, frequency of the applied voltage, and the presence of impurities. This makes the relation between current and voltage non-unique in some cases.

Electrical Resistance

Electrical Resistance is a measure of how much a material opposes the flow of electric current. It quantifies how difficult it is for electric charge to pass through a conductor

or component. Understanding electrical resistance is crucial for analyzing and designing electrical circuits.

Colour Code for Carbon Resistors

Colour Code for Carbon Resistors is a system used to identify the value of a resistor through a series of coloured bands printed on its body. 

Each colour represents a specific digit or multiplier, and the combination of these colours gives the resistance value of the resistor. This code system simplifies the process of reading resistor values without needing to measure them directly.

Here is a overview of how the colour code works:

First Band : Represents the first significant digit of the resistor value.

Second Band : Represents the second significant digit.

Third Band : Represents the multiplier (which tells you the power of ten by which the combined digits should be multiplied).

Fourth Band (if present) : Represents the tolerance, which indicates how much the actual resistance might vary from the stated value.

What Are Kirchhoff’s Rules?

Kirchhoff’s Rules are fundamental principles used to analyze electrical circuits. They are important for solving complex circuits involving multiple resistors, power sources, and other components. There are two primary rules:

1. Kirchhoff’s Voltage Law (KVL)

Statement : The algebraic sum of all the voltages around any closed loop in a circuit is zero.

Explanation : KVL is based on the conservation of energy. In a closed circuit loop, the total amount of energy gained from voltage sources (like batteries) must be equal to the total amount of energy lost in resistive elements (like resistors). Therefore, when you sum up all the voltage rises and drops around a loop, they must add up to zero.

2. Kirchhoff’s Current Law (KCL)

Statement : The sum of currents entering a junction (or node) in a circuit is equal to the sum of currents leaving the junction.

Explanation : KCL is based on the principle of conservation of electric charge. At any electrical junction, the amount of current flowing into the junction must equal the amount of current flowing out. This ensures that charge is neither created nor destroyed at the junction.

Potentiometer

A potentiometer is a versatile electrical device used to measure and compare potential differences (voltages) with high accuracy. It operates based on the principle of measuring voltage by balancing it against a known reference voltage.

Combination of resistors

Resistors are objects used to restrict the flow of charges in any conductor. However, these individual resistors can be arranged in different patterns to obtain different results. Resistors can be connected in 2 main ways:

In series

In parallel

Resistors in parallel

Resistors in parallel means when resistors are connected one below the other. All ends are connected to a common junction.

The above image shows that four resistors, R1, R2, R3, and R4, are connected in parallel. A potential difference V is applied at its ends.

Some important properties

Equivalent resistance R is

1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4

The potential difference across each resistor is the same.

The electric current ‘I’ drawn from the source equals the sum of currents flowing through individual currents.

I = I1 + I2 + I3 + I4

Ans: Carbon resistors use coloured bands to represent resistance values.

1st & 2nd bands: Significant digits

3rd band: Multiplier

4th band: Tolerance Example: Red (2), Violet (7), Orange (×1000), Gold (±5%)

Q8. How are resistors connected in series and parallel?

Ans:

Series: Req=R1+R2+R3+...R_{eq} = R_1 + R_2 + R_3 + ...Req​=R1​+R2​+R3​+... Same current flows through all resistors.

Parallel: 1Req=1R1+1R2+...\frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + ...Req​1​=R1​1​+R2​1​+...

Voltage across each resistor is the same.

Q9. What are current carriers in different states of matter?

Ans:

Solids (metals): Free electrons

Liquids: Ions (cations and anions)

Gases: Electrons and ions (only when ionized)

Q10. What is a potentiometer and its application?

Ans: A potentiometer is an instrument used to measure potential differences accurately by balancing them against a known voltage. It is commonly used in comparing emf of cells and calibrating voltmeters.

Q11. Why is electric current considered a scalar quantity?

Ans: Despite having a direction, electric current is considered scalar because it does not follow vector addition laws and only magnitude matters in calculations.

Q12. What is the unit of resistivity and conductivity?

Ans:

Resistivity (ρ): ohm-meter (Ω·m)

Conductivity (σ): siemens per meter (S/m)

Q13. How does temperature affect resistance?

Ans: In most conductors, resistance increases with temperature due to increased collision of electrons. In semiconductors, resistance typically decreases with temperature.

Top 7 Mistakes to Avoid While Preparing for NDA 2 2025 Exam

Top 7 Mistakes to Avoid While Preparing for NDA 2 2025 Exam | Shield Defence Academy

The NDA 2 2025 Exam is more than just a test—it’s your ticket to becoming a proud officer in the Indian Armed Forces. Thousands of aspirants dream of clearing it, but only a few make it. Why? Most candidates make basic but costly errors that could’ve been easily avoided. If you’re serious about your goal, then understanding the Top 7 Mistakes to Avoid While Preparing for NDA 2 2025 Exam is your first real step toward success.

Why Candidates Fail Despite Hard Work

You might be putting in hours every day, burning the midnight oil, and skipping weekends—but still not getting the results. Why? Because effort without strategy leads nowhere. Mistakes like ignoring the syllabus or neglecting your physical fitness can undo months of hard work. Don’t let these slip-ups sabotage your dream.

Top 7 Mistakes to Avoid While Preparing for NDA 2 2025 Exam

1. Ignoring the Syllabus and UPSC Pattern

This is the most common blunder. Aspirants randomly start preparing from books or YouTube videos without even glancing at the official UPSC NDA syllabus.

Why it matters: UPSC sticks to a defined pattern. If you know what topics to expect, you can study smarter, not harder.

Fix it: Download the latest NDA syllabus and analyze previous years’ papers to understand which topics are most important.

2. Poor Time Management

Balancing NDA prep along with school, tuition, or college is tough. But what’s worse is not having a daily routine.

Symptoms of poor time management: Cramming at the last minute, skipping subjects, or focusing only on favorites.

Solution: Create a timetable that includes study time, breaks, revision, and mock tests. Stick to it!

3. Not Practicing Mock Tests Regularly

Many students underestimate the power of mock tests. They think revising the syllabus is enough. Wrong!

Why mocks help: They train your brain to handle pressure and time constraints.

Shield Defence Tip: Take at least one full mock test every week. After the test, analyze what went wrong and improve.

4. Overlooking English and General Ability Test (GAT)

GAT makes up 600 out of 900 marks in the written exam. Yet, most students only focus on Maths.

Common mistake: Ignoring English grammar, comprehension, current affairs, and science.

What to do: Read newspapers daily, solve English MCQs, and practice current affairs weekly.

5. Skipping NCERT Books

NCERT books from Class 6 to 12 form the backbone of NDA preparation, especially for Maths, Physics, Chemistry, and Geography.

Why students skip them: They think NCERTs are too basic or outdated.

Reality check: Around 60% of NDA questions are NCERT-based. Don’t make the mistake of skipping them.

6. Avoiding Physical Fitness and Medical Standards

NDA isn’t just about passing the written test. You also need to clear SSB interview and medical fitness.

Blunder: Ignoring fitness until the last moment.

Fix: Start running, do push-ups, sit-ups, and improve your stamina now—not after the written test.

7. Lack of Guidance and Coaching

Self-study is great, but sometimes, you need expert guidance to avoid wasting time and effort.

Why it matters: You need someone to correct your mistakes, track your progress, and provide direction.

Solution: Join reputed coaching like Shield Defence Academy where you get subject-wise coaching, mock tests, physical training, and SSB guidance.

How to Rectify These Mistakes

Here’s how to bounce back stronger:

Make a fresh study plan aligned with the UPSC syllabus.

Dedicate 2 hours to GAT and English every day.

Practice 3–4 mock tests monthly.

Start your day with a physical workout.

Refer to NCERT books for basic understanding.

Take regular feedback from mentors or join structured coaching.

Why Shield Defence Academy Recommends Fixing These Mistakes Early

Shield Defence Academy has trained hundreds of NDA qualifiers, and we’ve seen the same pattern every year—those who avoid these mistakes crack the exam confidently.

What we offer:

NDA Foundation Courses

NDA + Schooling Program

Physical Fitness Sessions

Daily Mock Tests

Personal Mentorship and Doubt Clearing

Avoiding these mistakes with us ensures a much higher chance of success.

Additional Tips for NDA 2 2025 Preparation

Use a planner: Track your goals and achievements daily.

Group Study: Helps with peer learning and motivation.

Stay updated: Watch weekly current affairs videos or read monthly compilations.

Use smart apps: For vocabulary, current affairs, and Maths formulas.

Reward yourself: Celebrate small wins to stay motivated.

Conclusion for Top 7 Mistakes to Avoid While Preparing for NDA 2 2025 Exam

Success in the NDA 2 2025 Exam isn’t just about hard work—it’s about smart preparation. Knowing the Top 7 Mistakes to Avoid While Preparing for NDA 2 2025 Exam will save your precious time and effort. So, now that you know what not to do, are you ready to prep like a future officer?

Quizzes, worksheets, games, and assignments make the learning process fun and effective.

6. Parent Monitoring & Reports

The best schools involve parents through progress reports, PTMs, and real-time dashboards to track how well their child is performing.

Benefits of Enrolling in a Video-Based School

Whether your child is in Kindergarten or preparing for board exams, video study offers multiple benefits:

Learn at your own pace

Stay safe and study from home

Get personal attention in small batch sizes

Watch lessons multiple times for full clarity

No travel time or pressure from crowded classrooms

Most importantly, students build confidence, discipline, and curiosity, which are essential traits for lifelong success.

Is Video Study Right for Your Child?

Finds textbooks boring or hard to follow

Needs flexibility in learning time

Misses school often due to health or travel

Learns better through visuals and examples Then a top online school with video study might be the perfect solution.

Many students today score better in exams and feel more confident when they switch to this modern learning approach.
