How is a fuse put in an electric circuit? State the purpose of using a fuse in a circuit.
The fuse wire is stretched between the two metallic terminals T1 and T2 in a porcelain holder (since porcelain is an insulator of electricity). This holder fits into a porcelain socket having two metallic terminals to which the live wires of the circuit are connected. The figure below is showing the fuse arrangement.
A fuse is connected with each electrical appliance to safeguard it from the flow of excessive current through it.
