Question 12.21: Determine the true power and the reactive power in Figure 12...
The true power, P_{true}, is always zero for an ideal capacitor. The reactive power is determined by first finding the value for the capacitive reactance and then using
Equation 12-30 : P_{r}= \frac{V^{2}_{rms} }{X_{C}}.
P_{r}= \frac{V^{2}_{rms} }{X_{C}} = \frac{(2 \ V)^{2}}{7.96 \ k\Omega } = 503\times 10^{-6} VAR = 503 \ \mu VAR
