electric circuit​

Answer 1

Answer:

Electric Bulb: In an electric bulb, the filament of bulb gives light because of heating effect of electricity.

Electric fuse is made of metal or alloy of metals, such as aluminium, copper, iron, lead, etc. In the case of flow of higher voltage than specified, fuse wire melts and protects the electric appliances.

Answer 2

Explanation:

The electric fuse works on the principle of the heating effect of electric current. It consists of a piece of wire made of a metal or an alloy of low melting point. As the current increases beyond a limit, the wire in the electric fuse melts and breaks off. The fuse is then said to have blown off.
