voltage

Also known as electric tension, tension

Voltage, also known as (electrical) potential difference, electric pressure, or electric tension, is the difference in electric potential between two points. In a static electric field, it corresponds to the work needed per unit of charge to move a positive test charge from the first point to the second point. In the International System of Units (SI), the derived unit for voltage is the volt (V).

AI overview

Voltage is the difference in electrical potential between two points, often thought of as the electrical "pressure" that pushes electric charge from one location to another. It measures how much work is needed to move a unit of electric charge between those two points, and is expressed in units called volts.
