Q. What is a fuse wire?
i) Fuse wire is an alloy of lead 37% as well as tin 63%. It is linked in series in an electric circuit.
ii) It has high resistance as well as low melting point.
iii) When large current flows by a circuit due to short circuiting the fuse wire melts due to heating and hence the circuit becomes open. The electric appliances are put away from damage.
