Potential difference: Learn what potential difference (voltage) means in

Learn what potential difference (voltage) means in simple terms. Understand its definition, formula, unit (volt), and how it's measured using a voltmeter with easy examples. The potential difference between two points in an electric field, often referred to as voltage (V), is a measure of the electric potential energy difference per unit charge between those two points. It represents the work done per unit charge to move a positive test charge from one point to the other against the electric field. Electric potential (also called the electric field potential, potential drop, the electrostatic potential) is the difference in electric potential energy per unit of electric charge between two points in a static electric field. The potential difference between two points in an electric circuit is defined as the work done to Move unit Electric Charge from one Point to another in an electric circuit.
