Alternating Current: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Alternating Current. Understanding the underlying formula is key to arriving at the correct answer below:

The phase difference between voltage $V = 200 \sin(100t)$ and current $I = 5 \sin(100t - \pi/2)$ is $\phi = \pi/2$.
Power factor of the circuit is $\cos\phi = \cos(\pi/2) = 0$.
Average power consumption is $P = V_{rms} I_{rms} \cos\phi$.
$P = V_{rms} I_{rms} \times 0 = 0 W$.
