This tutorial is a practical demonstration in our series, "How to convert an Arduino PWM signal to an Analog signal (DAC)." In this video, we bring the simulation into a real-world scenario by breadboarding the circuit and porting our Arduino IDE code into the VS Code environment with PlatformIO.

In this experiment we use an NTC (Negative Temperature Coefficient) Thermistor whose resistance varies based on the temperature it is exposed to, this properties is then used to control the voltage drop across the resistor and in return set up an appropriate voltage at the Gate of the MOSFET to turn it on, this voltage is called Vth (Threshold voltage).

In this tutorial take a look on how to calculate the burden impedance of a current transformer and its Volt-ampere (VA) ratings, this is important in the process of current transformers selection and power system network design and protection requirement.

In this Tutorial we see how to calculate the per-unit value on both the primary and the secondary of the transformer given only the primary actual impedance, to achieve that we make use of the transformer ratios formula.
