In any Inductor or capacitor, this angle is 90 degrees, which makes the power Zero. For a capacitor, the Reactance is Inversely proportional to Frequency, so the value of 45 Ohms and 22.5 Ohms is the Reactance, not the Resistance. For an understanding, assume that the Reactance is the Resistance with a 90 degree phase factor.
Do capacitors have any resistance when uncharged? :
So, talking ideals here, ignoring leakage current or whatever. You charge a capacitor with a battery (DC). The system has reached steady state. The capacitor is charged.

For a perfect capacitor, voltage drop always lags current by 90°, and so a capacitor''s impedance phase angle is said to be -90°.
