# A charge of 6 C passes through a circuit every 3 s. If the circuit can generate 4 W of power, what is the circuit's resistance?

$\text{The current in the circuit"(I)="Charge passing through it"/"Time}$
$= \frac{6 C}{3 s} = 2 A$
Now $\text{Power} \left(P\right) = {I}^{2} \times R$, where R = Resistance
So$R = \frac{P}{I} ^ 2 = \frac{4}{2} ^ 2 = 1 \Omega$
