Question

A circuit with a resistance of `8 Omega` has a fuse with a capacity of `3 A`. Can a voltage of `15 V` be applied to the circuit without blowing the fuse?

Answer 1

Yes

Explanation:

Ohm's Law applies here. The voltage `V`, the current `I` and the resistance `R` have the relationship `V = I*R`
Rearranging, `I= V/R`
`I = 15/8` which is `<2`

The answer is yes - the voltage can be applied without blowing the fuse.
