Question

For an LCR series circuit at resonance, the incorrect statement is

• A. Power factor becomes one
• B. The phase angle between voltages across resistor and source is \(90^\circ\)
• C. Power dissipation is maximum
• D. Impedance is minimum

Hint:

At resonance in a series LCR circuit, \[ \boxed{ X_L=X_C,\qquad Z=R. } \] Therefore, \[ \boxed{ \phi=0^\circ,\qquad \text{Power factor}=1,\qquad I_{\max},\qquad P_{\max}. } \]

Answer 1

The Correct Option is B
