Question

Give two advantages of heating effect of electric current.
​

Answer 1

used in home appliances such as room heater , water heater

it is also used in electric motors

Answer 2

Explanation:

Advantages of Heating Effects of Electric Current:

1. In Electrical Heating Devices; the conductor has a High electrical resistivity. Hence, considerable amount of electric energy is lost in the form of heat, which is utilised for heating rooms and confined areas.

2. In Making Fuse Wires: The fuse wire is made of a material of high electrical resistivity, and has a low melting point. As a result, if a current higher than the specified value flows through the circuit, the fuse wire gets heated up instantaneously, and melts, as a result.
