Phase Relationships in AC Circuits
When capacitors or inductors are involved in an AC circuit, the current and voltage do not peak at the same time. The fraction of a period difference between the peaks expressed in degrees is said to be the phase difference. The phase difference is <= 90 degrees.
Complex Numbers, Phasors And Phase Shift
Capacitors and inductors are extremely common components, and consequently phase differences are a fundamental characteristic of AC systems. The phase relationships created by inductors and capacitors are described using the words leading and lagging .

Impedance, the vector sum of reactance and resistance, describes the phase difference and the ratio of amplitudes between sinusoidally varying voltage and sinusoidally varying current at a given frequency.
What is a Pure Capacitor Circuit?
The values of voltage and current are not maximised at the same time because of the phase difference as they are out of phase with each other by an angle of 90 degrees. The phasor diagram is also shown in the waveform indicating that the current (I m ) leads the voltage (V m ) by an angle of π/2.

Capacitive reactance is the opposition that a capacitor offers to alternating current due to its phase-shifted storage and release of energy in its electric field. Reactance is symbolized by the capital letter "X" and is …
Run Capacitor vs. Start Capacitor: What''s the Difference?
If a motor''s run capacitor fails, it can cause the motor to be unable to start and/or operate properly. This is because the missing capacitor prevents the proper phase difference between windings which results in a lack of torque for starting of the motor.
