# A charge of 30 C passes through a circuit every 5 s. If the circuit can generate 27 W of power, what is the circuit's resistance?

$R = \frac{9}{13} o h m$

#### Explanation:

$P = {I}^{2} \cdot R$

and$I = \frac{C}{t} = 6 A$

therefore $27 = 36 \cdot R$
by the first formula.
there fore $R = \frac{9}{13} o h m$
