Question 196: AC fundamentals

Question

An ac source is connected in given series LCR circuit. The rms potential difference across the capacitor of $$20 \mu \mathrm{F}$$ is __________ V.

Accepted Answer

$$\begin{aligned}
& \left(V_{r m s}ight)_c=\frac{V_{r m s}}{Z} X_c \
& =\frac{50}{\sqrt{(500-100)^2+300^2}} 	imes 500 \
& =50 \mathrm{~V}
\end{aligned}$$
