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

the current is given by the charge that flow in 1 second than 6C/3s = 2 Ampère. the electric power is given by $P = R {i}^{2}$ then $R = \frac{P}{i} ^ 2 = \left(6 W\right) {\left(/ 2 A\right)}^{2} = 1 , 5 O h m$
