Impedance and Power Factor in LCR Circuit
Impedance:
Inalternating current circuit the ratio of potential difference across the circuit and the current flowing therein is termed as impedance and is denoted by Z. Basically impedance of an AC circuit is the resistance offered by AC circuit to the flow of alternating current through it.
In an AC circuit contains pure inductance the current through the inductance is also alternating and sinusoidal in nature having the same frequency of alternation, but lags behind applied voltage by an angle pie/ 2 (90°). The current in inductance L is obtained by dividing the voltage across it by jwL. Thus impedance of an inductance is jwL.
