Primary Purpose of an Electric Fuse in a Household Circuit:
The primary purpose of an electric fuse in a household circuit is to protect the circuit and appliances from overcurrent.
- Overcurrent Protection: A fuse is designed to break the circuit if the current exceeds a safe limit, preventing damage to the wiring and appliances.
- Working Principle: A fuse consists of a metal wire or strip that melts when the current flowing through it exceeds a specified value. This interruption of the circuit prevents potential hazards like overheating, short circuits, or fires due to excess current.
In summary, the electric fuse acts as a safety device to prevent electrical overload and avoid damage or fire in the household circuit.
