Question
Safety fuse wire used in domestic electrical appliances
is made of metal of lowSolution
The fuse wire is based on the Joules law of heating which says that when the electric current is allowed to pass through a conductor, the conductor heats up and is proportional to the square of current. The main object of using fuse wire in electric circuit is to provide protection against short circuit or overload current. For this purpose, the material used as fuse wire should have high resistance and low melting point.
