A FUSE in a domestic electrical circuit:
ASteps up voltage from 220V to 11,000V for the line
BConverts AC supply to DC for sensitive appliances
CStores electric charge for later use by appliances
DMelts and breaks the circuit when current exceeds a safe limit
Answer & Solution
Correct answer: D. Melts and breaks the circuit when current exceeds a safe limit
A fuse is a thin wire with low melting point that MELTS when current exceeds the safe value, breaking the circuit. Modern homes use MCBs (resettable) instead. Both protect from short-circuits and overloading.
