Question

what is a fuse how does it work

Answer 1

The fuse breaks the circuit if a fault in an appliance causes too much current flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.

Answer 2

Hope it helps...!!!!

--------------------------

=> A fuse is a small conducting wire of low melting point which protects the household electrical system from getting damaged due to unusual high current.


=> The unusual high current may be due to short circuit, power fluctuation in the electric line etc.The fuse wire is made of conducting alloy of very low melting point. It is rated according to the desired current required by an appliance. If the current is more than the rated value, the fuse wire heats up and melts to stop the flow of current.
