Assertion (A): A series LCR circuit behaves as a pure resistive circuit at resonance. Reason (R): At resonance, X_L = X_C gives ω=1/(√ LC).

Assertion (A) : A series LCR circuit behaves as a pure resistive circuit at resonance. Reason $\displaystyle (R): \quad$ At resonance, $\displaystyle \mathrm{X}_{\mathrm{L}}=\mathrm{X}_{\mathrm{C}}$ gives $\displaystyle \omega=\frac{1}{\sqrt{\mathrm{LC}}}$.
