In an ac circuit the current lags behind
WebSince, current lags behind the voltage in phase by a constant angle, then circuit must contain R and L.We find that in RL circuit, voltage leads the current by a phase angle ϕ, … WebMay 1, 2024 · Because inductors are made to react against the change in current, it causes it to lag behind the voltage. When you apply a voltage to an inductor, you make a magnetic field. Henceforth, if the magnetic field varies with respect to time, there is an electric field that opposes the magnetic field inside the inductor.

Did you know?
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. 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 AC circuit, the current lags behind the voltage by π/3. The components of the circuit are A R and L B L and C C R and C D Only R Hard Solution Verified by Toppr Correct option … http://hyperphysics.phy-astr.gsu.edu/hbase/electric/phase.html
WebThis results in a voltage wave that is -90° out of phase with the current wave. Looking at the graph, the current wave seems to have a “head start” on the voltage wave; the current “leads” the voltage, and the voltage “lags” behind the current. Voltage lags current by 90° in a pure capacitive circuit. http://www.differencebetween.net/technology/difference-between-leading-and-lagging-power-factor/
