What term is used to describe the difference in electric potential between two bodies?

The term used to describe the difference in electric potential between two bodies is "Voltage." Voltage, also known as electric potential difference, indicates how much potential energy per unit charge is available to move electric charges through a circuit. It serves as the driving force that pushes electric current through a conductive path.

Voltage is measured in volts (V) and is essential in understanding electrical circuits. It determines how much energy is transferred when charges move between two points. This concept is foundational in electronics and electrical engineering, as it helps predict how much current will flow in response to applied voltage in a circuit.

In contrast, current refers to the flow of electric charge, resistance is a measure of how much a material opposes the flow of current, and capacitance is related to a component's ability to store electric charge. Each of these terms is important in the field of electricity, but voltage specifically addresses the potential difference between two points, making it the key concept in this instance.
