Therefore a phase shift is occurring in the capacitor, the amount of phase shift between voltage and current is +90° for a purely capacitive circuit, with the current LEADING the voltage. The opposite phase shift to an inductive circuit.
The phase difference is <= 90 degrees. It is customary to use the angle by which the voltage leads the current. This leads to a positive phase for inductive circuits since current lags the voltage in an inductive circuit. The phase is negative for a capacitive circuit since the current leads the voltage.
Capacitive Circuit: By the same token, and as shown in Figure 3b, for a capacitor in an AC circuit the current leads the voltage by 90°. That is, for a capacitor the case is in the opposite way of that for an inductor. Figure 3b Current due to a capacitor in a sinusoidal wave AC circuit.
The phase is negative for a capacitive circuit since the current leads the voltage. The useful mnemonic ELI the ICE man helps to remember the sign of the phase. The phase relation is often depicted graphically in a phasor diagram. It is sometimes helpful to treat the phase as if it defined a vector in a plane.
The phase relationships created by inductors and capacitors are described using the words leading and lagging. In a DC system, a capacitor’s voltage reaches the maximum value after its current has reached the maximum value; in an AC system, we say that the capacitor creates a situation in which voltage lags current.
As explained above, capacitors and inductors create phase differences between a circuit’s voltage and current waveforms. Capacitors and inductors are extremely common components, and consequently phase differences are a fundamental characteristic of AC systems.
