Answer & Solution
Correct Answer
(D) A
Step-by-step Solution
Detailed explanation
The circuit is a shunt clipper with the diode's anode connected to the top wire and cathode to the bottom (common) wire — diode points downward. During positive half-cycle (\(V_{in} > 0\)): diode is forward-biased \(\Rightarrow\) acts as short circuit \(\Rightarrow\)…
