Question

6. How does use of fuse wire protect electrical appliances?

Answer 1

Hi _______

An electrical fuse works by breaking the circuit when there is a fault in an appliance that causes too much current to flow.

The wire within the circuit melts due to the heat generated when the current going through the circuit is too great.

How it work?

As the current in a wire increases so does the heat generated. A fuse is simply a thinner piece of wire in the circuit. If the current gets too high the thin wire will melt and stop the current.
hope it help

Answer 2

Answer:

The fuse breaks the circuit if a fault in an appliance causes too much current to 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.
