Question

A circuit with a resistance of `6 Omega` has a fuse with a capacity of `5 A`. Can a voltage of `57 V` be applied to the circuit without blowing the fuse?

Answer 1

No, the fuse will blow.

Explanation:

Ohm's Law gives us:

`V=IR`

`:.I=V/R=57/6=9.5"A"`

So you can see that too much current will be drawn through the fuse which is only rated at `6Omega` so it will blow.
