Question

A circuit with a resistance of `3 Omega` has a fuse with a capacity of `2 A`. Can a voltage of `5 V` be applied to the circuit without blowing the fuse?

Answer 1

Yes, it can be applied.

Explanation:

By Ohm's law ,
`V= IR` or `I= V/R`

`I`= `5/3`= `1.6` `A`
Current in circuit is `1.6` amperes. Fuse is `2` `A`. So it will not blow.
