Reactive Power and Power Decomposition Quiz

$p(t) = \frac{1}{2} V_m I_m \cos(\theta_v - \theta_i) + \frac{1}{2} V_m I_m \cos(2\omega t + \theta_v + \theta_i)$ (correct)

$p(t) = \frac{1}{2} V_m I_m \cos(\theta_v - \theta_i)$

$p(t) = V_{max} I_{max} [\cos(\theta_{vi}) - \cos(2\omega t - \theta_{vi})]$

$p(t) = P + Q(t)$

$S = P + Q$

$S = V I$

$S = V_{max} I_{max} [\cos(\theta_{vi}) - \cos(2\omega t - \theta_{vi})]$

$S = V I cos\theta + jV I sin\theta$ (correct)

P represents system voltage profile and Q supports the system electromagnetically.

P represents the ability to perform useful work and Q supports the system electromagnetically. (correct)

P represents system frequency and Q supports the ability to perform useful work.

P represents system frequency and Q supports system electromagnetically.
