Question
A fuse is used in an electrical circuit to
- Indicate the consumption of power
- Maintain a constant voltage
- Maintain the constant current
- Break the circuit in case of excess current
Hint:
Break the circuit in case of excess current
The correct answer is: Break the circuit in case of excess current
Fuse wire is used in electric circuits to prevent the excess current flowing into the circuit and therefore preventing the appliances from getting damaged as it melts for the purpose of breaking a circuit in the event of excessive current.
