Question

Explain briefly how a fuse protects an electric circuit.
One Line Answer
Advertisements

Solution

The fuse helps to control the maximum current in an electrical circuit. The fuse protects an electrical circuit by melting and breaking the circuit, whenever the current exceeds the pre-determined limit in the circuit. Due to low melting point, the fuse wire melts and then breaks the circuit.
