# 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?

1.36 ohm

#### Explanation:

Current $I = \frac{q}{t}$

$q = 40 C$
$t = 8 s$

Therefore $I = 5 A$

Power $P = {I}^{2} R$

$P = 34 W$
Substituting the value of ${I}^{2}$
We get $R = 1.36 o h m$
