Question

A 220 V ac supply is connected between points A and B as shown in the figure. The potential difference across the capacitor C is (A) 0 V (B) 110 V (C) 220 V (D) 220√2 V

During positive half cycle, p-n junction conducts. ∴ Potential difference across C = Peak voltage of given ac voltage = V0 = Vrms √2 = 220√2 V

Q. A 220 V ac supply is connected between points A and B as shown in the figure. The potential difference across the capacitor C is

$0 V$

$110 V$

$220 V$

$2202 V$

During positive half cycle, p-n junction conducts.
$∴$ Potential difference across C
= Peak voltage of given ac voltage
$= V_{0} = V_{r m s} 2 = 2202 V$
