Question

What is a fuse wire? How they are helpful to the circuit.

Answer 1

⭕️A Fuse is a safety device which prevents Excessive Current From Flowing Into The Circuit.

⭕️The Fuse Is Made Up Of Alloy which is a High Resistance Wire But with Low Melting Point So When Large Amount Of Current Flows Through It Gets Heated Up And Melts!!!!!!!!!!!!!

⭕️If there was no fuse in the circuit, serious damage could be caused to the wiring.

⭕️It could get so hot and it catches fire, which might start a fire in the building.

⭕️That is why they use circuit breakers.

⭕️allowing excess electric current to flow through its circuit causes the wire inside the fuse to melt and breaka the flow of current.

⭕️a breaker acts kind of similar to a fuse in that it opens a circuit when excessive current flows.
