용량 리액턴스는
\displaystyle X_C = \dfrac{1}{2\pi f C} = \dfrac{1}{2\pi \cdot (100\ \mathrm{Hz}) \cdot (25.0 \times 10^{-6}\ \mathrm{F})} \approx 63.7\ \Omega
rms 전류는
\displaystyle I_{\mathrm{rms}} = \dfrac{V_{\mathrm{rms}}}{X_C} = \dfrac{50.0\ \mathrm{V}}{63.7\ \Omega} \approx 0.785\ \mathrm{A}
최대 전류는
\displaystyle I_{\max} = I_{\mathrm{rms}}\sqrt{2} = (0.785\ \mathrm{A})\sqrt{2} \approx 1.11\ \mathrm{A}
