An ac generator supplies a peak (not rms) voltage of 150 V at 60.0 Hz. The generator is connected in series with a 35-mH inductor, a 45-µF capacitor and an 85-$\varOmega$ resistor.
-What is the capacitive reactance for this circuit?
A)59 $\varOmega$
B)85 $\varOmega$
C)99 $\varOmega$
D)120 $\varOmega$
E)310 $\varOmega$

The capacitive reactance $X_C$ is calculated using the formula $X_C = \frac{1}{2\pi f C}$. Substituting $f = 60.0$ Hz and $C = 45 \times 10^{-6}$ F, we get $X_C \approx 59 \, \Omega$.
