Which of the following things is having the least resistance?
Open in App
Solution
The correct option is C Fuse wire
Bulb, fan, buzzer, room heater and other electrical appliances have considerable resistance due to which they opposes the flow of current. Fuse wires have negligible resisitance. Due to this property, they are used in the circuits without causing any power loss. Fuse wires also have a low melting point so that when excess current flows through them (i.e. more than the required current in the circuit), they melt and disconnect the circuit, thus, saving vital components and appliances.
