In an ac circuit the current in a capacitor
WebJun 10, 2024 · Capacitors in AC Circuits. Consider the circuit consisting of a capacitor (C) only. When an alternating voltage is applied across the capacitor, the capacitor being charged in one direction and then in the other as the voltage reverses. Due to the application of alternating voltage across the capacitor the electrons move to and fro around the ... Web1 day ago · Ans: The capacitor charges when a dc source is connected to a capacitor, and no current flows in the circuit thus the lamp does not light up. There will be no change even if C is reduced. The capacitor provides capacitive reactance (1/ C), and current flows in the circuit. Therefore, the lamp will shine.
