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 circuit comprises a diode and a resistor.
- The input voltage is denoted as \( V_{AB} = V_0 \sin \omega t \).
- The diode's characteristics result in a full-wave rectified output signal.
\[ {Output: Positive half-cycles are preserved; negative half-cycles are eliminated} \]
