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. \(V_{AB}\) would be zero at all times
• 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 circuit comprises a diode and a resistor.
• Input voltage is \( V_{AB} = V_0 \sin \omega t \).
• The diode's characteristics result in a full-wave rectified output waveform.

Output: Positive half-cycles are retained.
