Potential Difference Potential Difference :- Potential difference between two points in an electric field is defined as the work done by an external force per unit positive charge in moving it from one point to another against the electric field without acceleration. It is a scalar quantity and is measured in volts (V). Let the…
Electric Potential Electric Potential :- Electric potential, often denoted as V, is the amount of electric potential energy per unit charge at a point in an electric field. In simpler terms, it tells us how much work is needed to move a unit positive charge from a reference point (usually infinity) to a specific…
