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?

Options

  1. A220 ~V
  2. B110 ~V
  3. Czero
  4. D220 2 ~V

Correct answer

D. 220 2 ~V

Step-by-step solution

As p - n junction diode conducts electricity during only positive half-cycle (forward biased condition ). So, the potential difference across the capacitor is V= Peak value of input AC voltage aligned &=V₀=V_ rms 2 & Given, V_ rms =220 ~V & V=220 2 ~V aligned
