CBSE Physics Concept Notes : Advantages of Heating Effect of Current

BY Team Aakash Byjus

The heat produced due to the passage of an electric current through a conductor is called the  ‘Heating effect of current’.

 E.g., consider a bulb that is ON for some time and then switch it OFF. Now, if we touch the bulb, we feel it's hot.

This heating effect in the bulb results from an electric current that is supplied to the bulb through a wire.

The heating effect of current is useful in manufacturing room heaters and water heaters.

These heaters become hot when an electric current is supplied, but the wires remain cold.

 An electric current passing through the filament of the bulb produces a large amount of heat, due to which the bulb emits light & heat.

The working principle of an electric fuse is based on the heating effect of the current.

 Fuse is a safety device that prevents damage to electrical circuits and thus stopping the possible fire.

 Electric iron and geysers also work based on the effect of electric current.

Electric bulbs and lamps produce light due to the heating effect of the current.

 Electric stoves and induction cookers also work on the principle of the effect of electric current.
