What is Static Electricity? A Key Physics Concept for Defence Aspirants

Static electricity is a common yet fascinating phenomenon that plays a vital role in basic physics and frequently appears in competitive defence exams like NDA, CDS, and Air Force X & Y Group. Understanding it not only strengthens your physics fundamentals but also boosts your overall exam score.

How Does Static Electricity Work? Static electricity occurs when electric charges build up on the surface of an object, usually due to friction. When two objects are rubbed together—such as a balloon against your hair—electrons transfer from one material to the other. This imbalance of charges leads to a sudden release of energy when a path is available, often felt as a small shock.

This concept is visible in everyday experiences, such as clothes sticking together after drying or a spark when touching a metal object.

Why is it Important for Defence Exams? Questions on static electricity often appear in the general science or physics sections. A clear understanding of topics like conductors, insulators, electrostatic force, and electric field can give you a competitive edge.
