23.3: RLC Series AC Circuits

The phase angle is close to (90^o), consistent with the fact that the capacitor dominates the circuit at this low frequency (a pure RC circuit has its voltage and current (90^o) out of

15.3: Simple AC Circuits

The current through a capacitor leads the voltage across a capacitor by (pi/2) rad, or a quarter of a cycle. The corresponding phasor diagram is shown in Figure (PageIndex{5}). Here, the relationship between (i_C(t)) and (v_C(t)) is

Capacitor

The −j phase indicates that the AC voltage V = ZI lags the AC current by 90°: the positive current phase corresponds to increasing voltage as the capacitor charges; zero current corresponds

What is a Pure Capacitor Circuit?

In the pure capacitor circuit, the current flowing through the capacitor leads the voltage by an angle of 90 degrees. The phasor diagram and the waveform of voltage, current and power are shown below:

Series Resistor-Capacitor Circuits

Notice how the voltage across the resistor has the exact same phase angle as the current through it, telling us that E and I are in phase (for the resistor only). The voltage across the capacitor has a phase angle of -10.675°, exactly 90° less

Representation of AC Current And Voltage By Phasor Diagram

The current phasor lags behind the voltage phasor. By looking at the phasor diagram, we can tell how the circuit will behave, just like watching dancers can tell us what the next move might be.

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.

Capacitor AC Behavior

Phasor diagram You know that the voltage across a capacitor lags the current because the current must flow to build up the charge, and the voltage is proportional to that charge which is
