Answer 2

Heya friend,
Here is your answer:

When excess current flows through a circuit, the fuse wire melts and breaks off. By this, fuse prevents damage to electrical appliances.
A electric fuse is used to limit the current in an electric circuit which safeguards the circuit if the current in the circuit exceeds due to voltage fluctuations or short circuiting.
