WebSuch a set of conductors, a capacitor, essentially opposes changes in voltage, or potential difference, across its plates. A capacitor in a circuit retards current flow by causing the alternating voltage to lag behind the alternating current, a relationship in contrast to that caused by an inductor. WebIf the input is sinusoidal and the circuit makes no distortion, the output is also sinusoidal, but often its timing is in front (=leading) or behind (=lagging) the timing of the input voltage and the difference does not change as long as the frequency doesn't change. The lead or lag is usually expressed as degrees and called "phase shift". WebIn this problem, you will consider a series L−R−C.
