In an ac circuit the current lags behind
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. WebIn an A.C. circuit the current A Always leads the voltage B Always lags behind the voltage C Is always in phase with the voltage D May lead or lag behind or be in phase with the voltage Medium Solution Verified by Toppr Correct option is D) In an A.C. circuit, the current may depend on any circumstances. It may lag or lead or in phase of voltage.
In an ac circuit the current lags behind
Did you know?
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 … WebA leading waveform is defined as one waveform that is ahead of another in its evolution. A lagging waveform is one that is behind another. Example: Calculations for AC circuit analysis must take into consideration both amplitude and phase shift of voltage and current waveforms to be completely accurate.
WebA circuit consists of an AC voltage source, a 10-ohm resistor, and a capacitor, all connected in series. The magnitude of the impedance of the capacitor is also 10 ohms. Which of the following is true about the source voltage and the current through the circuit? a. Insufficient information is given. b. The source voltage will lag the current. c. WebAs with the purely inductive circuit, the current wave lags behind the voltage wave (of the source), although this time the lag is not as great: only 37.016° as opposed to a full 90° as was the case in the purely inductive circuit. Current lags voltage in a series L-R circuit.
