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 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
