23.2: Reactance, Inductive and Capacitive
For capacitors, we find that when a sinusoidal voltage is applied to a capacitor, the voltage follows the current by one-fourth of a cycle, or by a (90^o) phase angle. Since a capacitor can stop current when fully charged, it limits current and offers another form of AC resistance; Ohm''s law for a capacitor is [I = dfrac{V}{X_C},] where (V) is the rms …
