Question

A 220 V ac supply is connected between points A and B as shown in figure. What will be the potential difference V across the capacitor?

• A. 220 V
• B. 110 V
• C. 0V
• D. $220\sqrt{2}V$

Answer 1

Answer: (D)

$220\sqrt{2}V$

Answer 2

: Potential difference across capacitor,

$V =$peak voltage

$= V_{rms}\sqrt{2}$

$= 220\sqrt{2}V.$
