Question

Explain why are 13 a fuse is suitable for a circuit in which the greatest current is usually 10 A

Answer 1

Bez when the object which contains electric motors required more starting current then the current requirements which running which means starting current requirements is always more than the running current so if the fuse is of the rating with running current will be used then while starting of the motor if will fuse off bez of the more amount of the current flowing through the circuit.

so always fuse with higher rating Is used in the circuit then rating of the appliances.
