Answer 2

Question:

• When current is switched 'on' in a room-heater, it______

Answer :

When current is switched 'on' in a room-heater, it produces heat and starts working

• which is an example of " heating effect of electric current "

Know why ?

• When current flows through a conductor,  heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: The resistance, R of the conductor. A higher resistance produces more heat.

In Simpler words

• When a current passes through a wire, a part of the electrical energy is converted into heat energy and the wire gets heated. This is known as heating effect of electric current
