Question

A circuit with a resistance of `8 Omega` has a fuse with a capacity of `3 A`. Can a voltage of `25 V` be applied to the circuit without blowing the fuse?

Answer 1

Nope

Explanation:

Ohm's Law states that

`V=ItimesR`

Voltage should be

`V=8times3 = 24` volts.

But you want to apply 25 volts. You should either drop the circuit's resistance or choose a fuse that is able to handle this resistance.
