Which unit is used to measure voltage?

Voltage is the electrical potential difference that pushes current through a circuit. The unit used to measure this push is the volt (V); for higher voltages, kilovolts (kV) are used, where 1 kV equals 1000 V. This is distinct from other electrical quantities: resistance is measured in ohms, charge in coulombs, and power in watts. Since voltage is quantified by volts or kilovolts, this is the appropriate unit.
