Question

Which of the following is false about fuse?

A.A fuse controls the current that flows to the appliance.
B.A fuse increases the resistance in the circuit to minimize the current flow.
C.A fuse allows high current to flow through the circuit without damaging the appliance.
D.A fuse protects the wiring and the appliance in the circuit from overheating.

Answer 1

Hint: Here we should know about the fuse and its characteristics, a fuse is an electrical safety device built around a conductive strip that is designed to melt and separate in the event of excessive current

Step by step answer: A fuse usually has a low resistance resistor that acts as a special device to provide overcurrent protection, of either the load or source of circuit.
It neither increases the resistance of the circuit nor does it allow high current. That means it never increases the resistance in the circuit and it does not allow the high current in the circuit. Since it doesn't allow high current to pass in the circuit hence it also protects appliances from heating.
 Fuses are always connected in series with the circuit along the electrical components to protect from overcurrent passing through the circuit, so that when the fuse is open in the entire circuit and stops current passing through the electrical components. If the fuse connected in parallel with the circuit, it would not affect current passing through any of the other branches. . It controls the amount of current flowing in a circuit.

Hence the correct option is A

Note: It’s important to know the few application of fuse
It is the cheapest form of protection, and we don’t need to maintain it.
It operates automatically and requires less time as compared to circuit breaker
