The primary purpose of a fuse in an electric circuit is to protect circuits and appliances by stopping the flow of any unduly high electric current. It acts as a safety device. If a current larger than the specified value flows through the circuit, the fuse wire heats up and melts, breaking the circuit and preventing damage.

The primary purpose of a fuse in an electric circuit is to protect circuits and appliances from excessive current. Fuses act as safety devices by interrupting the circuit when the current exceeds a safe limit, preventing damage to connected devices or appliances. The fuse contains a thin wire that melts when exposed to high currents, breaking the circuit and disconnecting the power source. This intentional interruption prevents overheating, fires, or damage to sensitive electronic components. Fuses play a crucial role in electrical safety, safeguarding both circuits and appliances by responding to abnormal current conditions and preventing potential hazards.
