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

Exemplar Solutions Class 12 Physics Chapter 14 - 3

(a) 220V

(b) 110V

(c) 0V

(d) 220 √2 V

Answer:

The correct option is (d) 220 √2 V

Explanation:

V(max) will be the potential difference across the capacitor. It is given by:

{{V}_{\max }}={{V}_{rms}}\sqrt{2}=220\sqrt{2}V
