State, whether the following statements are true or false:
a) A generator works on the principle of electromagnetic induction.
b) A motor works on the principle of electromagnetic induction.

Answer:

a) True

Explanation:

A generator produces electricity by rotating a coil in a magnetic field.

An electric generator (dynamo) turns mechanical energy into electrical energy. Generators do not create electricity, but rather use mechanical energy to compel electric charges contained in their windings to travel via an external electric circuit. This flow of electrons is the generator’s output current.

b) False

Unlike a generator, an electric motor converts electricity into mechanical energy. They work on the basis of electromagnetism, where an electric current in a magnetic field produces a force. Motors are made up of various elements that work together to provide power. Direct current (DC) and alternating current (AC) both have advantages and disadvantages.
