Solution

Electromotive force (EMF):
The energy required to move a unit positive charge particle around an external circuit connected to a battery or cell. The force provides the current movement into a circuit. The emf example is battery voltage. EMF is also the terminal potential difference having zero current flows through the circuit.

The phenomenon on which electric generator works:

The electric generator operates on the electromagnetic induction phenomenon. In this phenomenon, the conductor held into the magnetic fields, due to this emf induced by the rotating magnetic fields on that conductor and as a result, the current induced in the conductor. With the help of this phenomenon, electricity is generated.


Thus, electromagnetic induction is the phenomenon on which an electric generator works.
