In the circuit shown, assuming the threshold voltage of the diode is negligibly small, then the voltage \( V_{AB} \) is correctly represented by:
In the circuit shown, assuming the threshold voltage of the diode is negligibly small, then the voltage \( V_{AB} \) is correctly represented by:
Show Hint
The Correct Option is B
Solution and Explanation
- The input voltage \( V_{AB} \) is given as \( V_0 \sin \omega t \).
- Due to the nature of the diode, the output waveform is a full-wave rectified signal.
\[ {Output: Only positive half-cycles remain} \]
