The key is to understand the phase difference, also known as the phase angle, If the AC source provides a voltage VR(t)=V0cos(?t), what is the current IR(t). For any capacitor, the degrees phase relationship between Vc and ic The 90 degrees phase angle results because ic depends on the rate of change of Vc Vt is the phasor sum of the two voltages Vr and Vc 90 degrees out of phase. This timing difference is called Phase Shift, f, 0° ≤ f ≤ 90°, and is measured in There is no Phase Shift between the Voltage and the Current in a Resistive.
