Question
A fuse is fixed in a circuit to
- Increase the amount of current
- Increase the power consumed in the circuit
- Safeguard against excessive current
- Decrease the amount of current
Hint:
Safeguard against excessive current
The correct answer is: Safeguard against excessive current
The main fuse is connected in the live wire so that if the current exceeds its rating, the fuse melts and breaks the circuit; thus, preventing the excessive current from flowing into the circuit.
