Question

How does use of a fuse wire protect electrical appliances?

Answer in Brief
Advertisements

Solution

Fuse wire has low melting point and high resistance. So, whenever there is surge in the electric current, the fuse wire melts and breaks the circuit. This prevents any damage to the electrical appliances. Thus, a fuse wire protects the electrical appliances.
