Among the following, the electric fuse is the safety device.
- An electric fuse is used for the purpose of protecting the electrical circuits.
- If there is an overflow of current through the electrical wires, the overload would result in overheating of the wires.
- As a result, the wires could melt and lead to fire and severe accidents.
- An electric fuse prevents this by breaking the circuit.
- They are made of wires with a very low melting point.
- Even a small overflow of current can easily melt the fuse wires and stop the current flow and prevent accidents.
