Question 146 of 190

When resonance is produced in a series LCR circuit, then which of the following is not correct?

Show answer and solution

Answer: (D) Impedance of the circuit is maximum.

Impedance (Z)(Z) of the series LCR circuit is
Z=R2+(XL−XC)2Z=\sqrt{R^2+\left(X_L-X_C\right)^2}
At resonance, XL=XC\mathrm{X}_{\mathrm{L}}=\mathrm{X}_{\mathrm{C}}
Therefore, Zminimum =RZ_{\text {minimum }}=R
