In an alternating current circuit
WebSep 12, 2024 · Since the current in the circuit is the rate at which charge enters (or leaves) the capacitor, iC(t) = dq(t) dt = ωCV0cosωt = I0cosωt, where I0 = ωCV0 is the current amplitude. Using the trigonometric relationship cosωt = sin(ωt + π / 2), we may express the instantaneous current as iC(t) = I0sin(ωt + π 2). WebMay 4, 2024 · 05/04/2024.

WebMar 26, 2016 · There are actually three ways you can measure voltage in an AC circuit. The three ways are: Peak voltage: A measurement of the largest voltage present between 0 V and the highest point on the AC cycle. It's the maximum voltage that the AC voltage attains. Peak-to-peak voltage: The difference between the highest and lowest peaks of the AC … WebAn electric current that frequently reverses direction is called an alternating current ( AC ). Once again, whether the intensity of the current remains constant is irrelevant. The …

WebOct 15, 2024 · If a resistor is placed across the live and neutral wires, the voltage across the resistor is alternating and thus, the current through the resistor is alternating. It's completely irrelevant to this result if the neutral wire is at 0V with respect to ground. – Alfred Centauri Oct 17, 2024 at 14:37 But the wire isn't.
