Question 23
How does use of a fuse wire protect electrical appliances?

Answer 1

Fuse wire has low resistance, it allows normal current to pass through it safely but if there is any short circuit, a fuse will blow out i.e fuse wire can’t withstand the heat produced by that current (infinite current) so it melts and breaks the circuit. In this way, the electrical appliances are saved from overheating.
