WebPhase. When capacitors or inductors are involved in an AC circuit, the current and voltage do not peak at the same time. The fraction of a period difference between the peaks expressed in degrees is said to be the phase difference. The phase difference is <= 90 degrees. It is customary to use the angle by which the voltage leads the current. WebDec 10, 2016 · In this type of circuit, the current lags behind the voltage by an angle of 90 degrees. So, the phase angle between v (t) and i (t) in the given circuit is 90°. Phasor Diagram: The clockwise direction is taken as the positive direction. ∴ We can conclude that the current (I) lags the voltage (V) in a purely inductive circuit. Important Points:

WebJul 7, 2024 · What is lead and lag power factor? A lagging power factor denotes that on the phasor diagram, the current lags (is behind) the voltage, and a leading power factor denotes that the current leads (is ahead) the voltage. For inductive loads (e.g. induction motors, coils, lamps), the current lags behind the voltage, thus having a lagging power factor. simply bread high wycombeWebIf 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". simply bread satellite beach
