Question

Which of the following is athe safety device

Answer 1

Answer:

Fuse wire is a safety device which is used to limit the current in an electrical circuit.

Fuse wire is used as a safety wire which is connected in series with the live wire. The fuse wire melts and breaks the electric circuit when there is a supply of large current or malfunctioning in the electric connections.

The advantage of using a fuse wire is that it protects the circuit and other electrical appliances by stopping the flow of excess current.

Following are the characteristics of fuse wire:

1. It has a high resistivity

2. It has a low melting point
