About these units
Voltage is the electric potential difference that pushes current through a circuit. The SI unit is the volt, one watt per ampere. Sensors and nerve signals are measured in millivolts or microvolts; mains supply is 230 V in Europe and 120 V in North America; transmission lines run at hundreds of kilovolts.
The CGS system's statvolt is exactly 299.792458 V, a value fixed by the speed of light.
