An AC voltage source with a frequency of $120 \mathrm{Hz}$ and an amplitude $V_{\max }=25 \mathrm{V}$ is connected across a capacitor with $C=1.5 \mu \mathrm{F}$ (Eig. P22.20). Draw a phasor diagram showing the voltage across and the current through the capacitor. What is the length of the phasor that represents the current across the capacitor? Be sure that your answer has the correct units.
