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

Options

  1. ACurrent in the circuit is in phase with the applied voltage.
  2. BInductive and capacitive reactances are equal.
  3. CIf R is reduced, the voltage across capacitor will increase.
  4. DImpedance of the circuit is maximum.

Correct answer

D. Impedance of the circuit is maximum.

Step-by-step solution

Impedance (Z) of the series LCR circuit is Z= R^2+ (X_L-X_C )^2 At resonance, X _ L = X _ C Therefore, Z_ minimum =R
