If the true power is  100 W and the reactive power is  100 VAR , the apparent power is
A)  141 W
B)  200 VA
C)  141 VA
D)  100 VA

Quizplus · Accepted Answer

The apparent power is calculated using the formula $S = \sqrt{P^2 + Q^2}$, where $P$ is the true power and $Q$ is the reactive power. Substituting $P = 100$ W and $Q = 100$ VAR, we get $S = \sqrt{100^2 + 100^2} = \sqrt{20000} = 141.42$ VA, which rounds to 141 VA.
