# A charge of 2 C passes through a circuit every 2 s. If the circuit can generate 7 W of power, what is the circuit's resistance?

Current($I$) flowing through the circuit is $\frac{q}{t}$ i.e $\left(\frac{2}{2}\right) A$ or $1 A$
If power is $7$ Watt,then from formula of power($P = {I}^{2} r$) we can write,
$7 = 1 \cdot r$ (where r is the resistance of the circuit)
So,$r = 7 o h m$
