Electric fuse is a SAFETY device that:
AIncreases the circuit current
BReduces power consumption
CMelts and breaks overload
DBoosts the supply voltage
Answer & Solution
Correct answer: C. Melts and breaks overload
1. A fuse is a thin wire with a low melting point connected in series with the appliance.
2. If current exceeds the rated value, Joule heating MELTS the fuse wire and BREAKS the circuit.
3. Prevents fire, overheating, and damage to costlier components.
