Solution

Step 1:Given
$V = 220 V$ and $V_{L} = 110 V$
Given that the circuit is at resonance.
Step 2:Estimate voltage across capacitor:
We know that during resonance $V_{L} = V_{C}$
Therefore, the potential drop across the capacitor is
$V_{C} = 110 V$
Hence, the potential drop across the capacitor is $110 V$ .
