The total energy required to send a unit positive charge round a complete electrical circuit is the
- kinetic energy
- potential difference
-
electromotive force
- electrical energy
The correct answer is: C
Explanation
Electromotive Force (EMF) refers to the total energy supplied by a source (like a battery) to move a unit positive charge around a complete circuit. It is measured in volts and indicates how much energy per unit charge is available to drive the current through the circuit.
