Electric Potential Difference Between Two Points, often referred to as voltage (V), measures the difference in electric potential energy per unit charge between two specific locations in an electrical circuit. It is one of the fundamental concepts in electrical engineering and is widely used in aircraft design for various electrical systems. The formula for electric potential difference (voltage) and its SI unit are as follows
Electric Potential Difference (Voltage) Formula: The formula for calculating electric potential difference (V) between two points is based on the work done (W) to move a positive test charge (q) from one point to another:
- V: Electric Potential Difference (Voltage), measured in volts (V).
- W: Work Done, measured in joules (J).
- q: Test Charge, measured in coulombs (C).
