Quizplus · Accepted Answer

The average power consumed by the circuit is given by the formula P = Vrms * Irms * cos(theta), where Vrms is the root-mean-square voltage, Irms is the root-mean-square current, and theta is the phase angle between the voltage and current. In this case, Vrms = 120 V, Irms = 0.5 A, and theta = 0 degrees. Therefore, P = 120 V * 0.5 A * cos(0 degrees) = 60 W.
