WebLeading and lagging current are phenomena that occur as a result of alternating current. In a circuit with alternating current, the value of voltage and current vary sinusoidally. In this type of circuit, the terms lead, lag, and in phase are used to … WebIn series LCR circuit, the phase angle between supply voltage and current is. In a series LCR circuit the voltage across an inductor, capacitor and resistor are 20 V, 20 V and 40 V respectively. The phase difference between the applied voltage and the current in the circuit is (a) 30° (b) 45° (c) 60° (d) 0°
WebNov 27, 2024 · For inductors in ac circuits, we find that when a sinusoidal voltage is applied to an inductor, the voltage leads the current by one-fourth of a cycle. The opposition of an inductor to a change in current is expressed as a type of ac reactance. This inductive reactance, which has units of ohms, varies with the frequency of the ac source. WebInductor in an AC circuit In a purely inductive circuit, we use the properties of an inductor to show characteristic relations for the circuit. Considering the flow of a time-dependent current I I through the circuit shown below …
