Question

In the circuit shown, assuming the threshold voltage of the diode is negligibly small, then the voltage \( V_{AB} \) is correctly represented by:

 

• A.
• B.
• C.
• D.

Hint:

For rectifier circuits, always analyze diode conduction in both half cycles of the AC signal.

Answer 1

The Correct Option is B

- The given circuit consists of a diode and a resistor.
- 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.
\[ {Output: Only positive half-cycles remain} \]
