The SI unit of electric potential or electromotive force.
The SI unit of electric potential or electromotive force. It's the potential across a conductor with one ohm resistance when one ampere of current flows. If you imagine water circulating round a system instead of electricity, electromotive force is the pressure difference that drives water around the circuit.
