In a series LCR circuit at resonance, the voltages across L and C are each $200$ V and the supply voltage is $50$ V. The voltage across R is
Answer: (A) $50$ V
Concept. At resonance $V_L$ and $V_C$ are equal and opposite, so they cancel.
Step 1. Apply. The whole supply voltage appears across R: $50$ V.
Answer. $50$ V (Option A).
