Mathematically, we say that the phase angle of a capacitor''s opposition to current is -90, meaning that a capacitor''s opposition to current is a negative imaginary quantity. (See figure above.) This phase angle of reactive opposition to current becomes critically important in circuit analysis, especially for complex AC circuits where reactance and resistance interact.

how a phase delay occurs in capacitors/inductors with visual images
Capacitors provide a phase delay between the current and voltage. Current leads the voltage by 90 degree. I was taught these only with the equations. But I want visual intuition, what happens in the capacitor that causes phase delay. The same applies to inductor.
Complex Numbers, Phasors And Phase Shift
Another way of describing the phase component is phase shift, meaning that the phasor conveys how much the signal has shifted relative to a signal that has zero phase. Mathematically, this zero-phase signal is a cosine waveform, but in practice AC signals don''t have a beginning or end, so you choose one of the signals and call it a cosine wave.
