Voltage is measured in which unit?

Explanation:
Voltage is the electric potential difference that pushes charges to move, and its unit is the volt. One volt is defined as the potential difference that would drive one ampere of current through one ohm of resistance, or equivalently one joule per coulomb (also one watt per ampere). In circuits, this relationship is expressed as V = IR, linking voltage to current and resistance, and P = VI for power. The other units—amperes for current, ohms for resistance, and watts for power—measure different quantities, not voltage.
