Question:

An alternating voltage of \( 250\,\text{V},\,50\,\text{Hz} \) is applied to a full wave rectifier. If the internal resistance of each diode is \( 10\,\Omega \) and the load resistance is \( 5\,\text{k}\Omega \), the peak value of output current is

Show Hint

Use peak voltage \( V_{rms}\sqrt{2} \) in AC calculations.

The Correct Option is B

Solution and Explanation

Concept: \[ I_{peak} = \frac{V_{peak}}{R} \]

Step 1:
Peak voltage.
\[ V_{peak} = 250\sqrt{2} \]

Step 2:
Total resistance.
\[ R = 5000 + 2\times10 = 5020\,\Omega \]

Step 3:
Current.
\[ I \approx \frac{250\sqrt{2}}{5020} \approx 0.07\,\text{A} \]
