12th Class Physics Semiconducting Devices Question Bank MCQs - Semiconductor Electronics: Materials, Devices and Simple Circuits

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

A) 220 V

B) 110 V

C) 0 V

D) 220\[\sqrt{2}\] V

Correct Answer: D

Solution :

Option [d] is correct.

Explanation: Potential difference across capacitors will be peak voltage when diode is in forward bias. Diode will be in forward bias when end A is at positive potential of cycle.

So potential at C = peak value of \[\operatorname{V}={{V}_{\operatorname{rms}}}\sqrt{\operatorname{V}}\]
