What is the function of a fuse in an electrical circuit?
ATo store electrical charge
BTo protect the circuit by breaking it during excess current
CTo increase voltage
DTo convert electrical energy into light
Explanation
A fuse contains a thin wire that melts and breaks the circuit when current flow exceeds a safe level, protecting appliances and wiring from damage or fire caused by overheating. Once a fuse blows it must be replaced, unlike a circuit breaker, which can simply be reset. Fuses remain a basic but essential safety component in household and industrial electrical systems.
