Amelting to break the circuit on high current
Bincreasing the current flowing in the circuit
Cstoring extra charge during a power surge
Draising the supply voltage to the appliance
Answer & Solution
Correct answer: A. melting to break the circuit on high current
1. A fuse is a short piece of thin wire with a low melting point placed in series.
2. If the current exceeds a safe value (overloading or short circuit), the fuse **melts and breaks the circuit**, stopping the current.
3. This prevents fire and damage to appliances.
