EVERYDAY SCIENCE

Detailed explanation-1: -Fuse wire has low melting point and high conductivity. It is connected in series with the appliance in a circuit. Whenever there is high electric current, more heat will be produced and it leads to the melting of fuse wire.

Detailed explanation-2: -If too much current flows, the fuse wire rises to a higher temperature and melts, thus opening the circuit, but destroying the fuse. A circuit breaker opens a circuit as soon as the current climbs to unsafe levels, and can be used repeatedly.

Detailed explanation-3: -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.

Detailed explanation-4: -Fuse is the weakest part of the circuit which melts and breaks the electric circuit in case of an overload.

Detailed explanation-5: -If a short circuit occurs-or even if too many appliances get hooked up to one wire so that too much current flows-the wire in the fuse heats up quickly and melts, breaking the circuit and preventing a fire from starting.
