Multiple Choice

Voltage is defined as which of the following?

Voltage is the potential difference between two points in an electrical circuit. It represents the electric potential energy per unit charge that can be converted into work as a charge moves from one point to another. This potential difference is what drives current through conductors, much like a pressure difference pushes water through a pipe. In practical terms, a voltmeter measures this potential difference across two points. Current is the rate of charge flow, not the push that starts it. Resistance is the opposition to current flow. Power is the rate at which energy is transferred.
