Question

A charge of `40 C` passes through a circuit every `8 s`. If the circuit can generate `34 W` of power, what is the circuit's resistance?

Answer 1

1.36 ohm

Explanation:

Current `I=q/t`

`q=40C`
`t=8s`

Therefore `I=5A`

Power `P=I^2 R`

`P=34W`
Substituting the value of `I^2`
We get `R=1.36 ohm`
