Question

state the characteristics of a series LCR AC resonance circuit​

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.

Answer 2

Answer:

(a) The impedance of the circuit is minimum

(b) The current in the circuit is maximum
