Question

(a) Explain the principle of an electric generator.
(b) State two ways in the which the current alternating current and direct current?

Answer 1

(a) An electric generator works on the principle of electromagnetic induction. It states that when a conductor is moved in a magnetic field, current is induced in the conductor.

(b) Two ways in which the current induced in the coil of a generator could be increased:

1. By using a coil with more turns
2. By using a coil with larger area
