Question

A diode is connected to 220 V (rms) ac in series with a capacitor as shown in figure. The voltage across the capacitor is –

• A. 220 V
• B. 110 V
• C. 311.1 V
• D. $\frac{220}{\sqrt{2}}$V

Answer 1

Answer: (D)

$\frac{220}{\sqrt{2}}$V

Answer 2

V_C = V₀ = $\sqrt{2}$V_rms= $\sqrt{2}$ × 220 volt
