Question

A circuit with a resistance of `7 Omega` has a fuse melts at `6 A`. Can a voltage of `11 V` be applied to the circuit without blowing the fuse?

Answer 1

Actual current in circuit= voltage divided by Resistance=11/7=1.571 amps.

Explanation:

Fuse blow only at 6 amps. Here we get current only 1.571 amps.It is safe to apply voltage.
