Question

In an L-C-R series AC circuit at resonance

• A. the capacitive reactance is more than the inductive reactance
• B. the capacitive reactance equals the inductive reactance
• C. the capacitive reactance is less than the inducive reactance
• D. the power dissipated is minimum

Answer 1

Answer: (B)

the capacitive reactance equals the inductive reactance

Answer 2

At resonance (series resonant circuit) $X_L = X_C$ $\Rightarrow Z_{ min} = R,$ ie, circuit behaves as resistive circuit.
