For a perfect capacitor, voltage drop always lags current by 90 o, and so a capacitor''s impedance phase angle is said to be -90 o. Impedances in AC behave analogously to resistances in DC circuits: they add in series, and they diminish in parallel. A revised version of Ohm''s Law, based on impedance rather than resistance, looks like this:
