In an ac circuit the current in a capacitor

WebIn a DC circuit, when a capacitor is connected to a voltage source, the current will flow for the short time required to charge the capacitor. In this section, we will learn the … WebApr 9, 2024 · If the capacitor is currently at -0.7 V, current will flow against the voltage direction of the AC source (negative you could call it). Conversely, if the AC source is at -0.5 V, while the capacitor is at 0.7 V, current will flow in the positive direction while the voltage source is negative.
