How does an Electric Fuse Work?
An electric fuse is a safety device. It helps avoid short circuits and thus helps in protecting the electrical appliances from getting damaged.
A fuse consists of a metal strip or a wire fuse element. When current starts flowing through the fuse element, heat is generated due to resistance of the fuse element. The fuse element is constructed in such a fashion that when normal current flows or a small current spike occurs it does not cause the fuse element to attain a high temperature. But when the current load is too high the fuse element rises to a high temperature and melts. Thus breaking the circuit and in turn saving the electrical appliance from damage.
