Electromotive Force & Internal Resistance

When a charge passes through the power supply, it gains electrical energy. The power supply is said to have an electromotive force, or emf. Electromotive force is measured in volts. Electromotive force is not a force. Instead, it is the energy gained by the charge that comes from the chemical energy of the battery.

External Power
