What is a circuit breaker and how is it different from a fuse? Why do we need these two different devices? DO NOT PLAGARIZE!

It's A device used to protect an electrical circuit from damage caused by overcurrent/overload or short circuit.Function: To interrupt current flow after protective relays detect a fault.Why do we need them : It disrupts the flow of a current if there's a short circuit or overload. In doing so, it can prevent damage to an electrical circuit and possibly appliances, electronics, and our home.

It's A device that protects circuits and appliances by stopping the flow of unduly high electric current.Function :The basic function of fuse is to prevent fire .It breaks electrical circuit if there occurs a fault in electrical appliances that causes too much current flow.why do we need them : Without a fuse, there are many possibilities for electrical fires or extreme damage to a circuit.

Hope it Helps
