Question

dèfine LCR series circuit? find expression for important ​

Answer 1

Answer:

Resonance occurs when XL = XC and the imaginary part of the transfer function is zero. At resonance the impedance of the circuit is equal to the resistance value as Z = R. At low frequencies the series circuit is capacitive as: XC > XL, this gives the circuit a leading power factor.

An LCR circuit, also known as a resonant circuit, tuned circuit, or an RLC circuit, is an electrical circuit consisting of an inductor (L), capacitor (C) and resistor (R) connected in series or parallel.
