Question

An electric fan/motor becomes warm when continuously used for a long time. Why?

Answer 1

Heat in electric appliance

Explanation:

The electric fan is run by a motor that converts electrical energy to mechanical energy. During this conversion, some amount of energy is lost in the form of heat energy and gets dissipated into the surroundings. This is the reason why electrical appliances, including the ceiling fan, become warm after continuously used for a long time. It is advised switch off the appliance for about 20-30 minutes and then start them again.
