What is the function of a fuse or circuit breaker in a circuit?
The function of the fuse or circuit breaker in a circuit.
Explanation of Solution
Introduction:
A fuse or a circuit breaker is the device of very low resistance and low melting point. If it fails in the circuit, then the circuit becomes an open circuit. The current cannot flow through open circuit.
The current in the circuit varies with the resistance of the circuit. If the resistance decreases, the current increases. In the fuse or circuit breaker, the fuse wire heats up when a high current flows across it. The wire melts and it stops to flow the current. The interruption in the supply save the other electrical devices in the home.
Conclusion:
The function of the fuse wire or circuit breaker is to stop the high current and to save the electrical devices in the home.
