The unit of measurement of EMF (Electromotive Force) is:
Answer: B
EMF is measured in volts.
Electromotive force is the energy a source such as a cell or generator gives each coulomb of charge that passes through it. Energy per unit charge, joules per coulomb, is the volt, the same unit as potential difference.
The ohm is the unit of resistance, the ampere of current and the watt of power, so none of them can measure an electromotive force.
