Name a safety device which is used to limit the current in an electrical circuit. The use of this device safeguards the circuit and the appliances connected in that circuit from being damaged

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:

  • It has a high resistivity
  • It has a low melting point
