Answer

To analyze the contribution from the diode D2 in a full wave rectifier circuit, we can follow these steps:

### Step 1: Understand the Full Wave Rectifier Circuit
A full wave rectifier circuit uses two diodes (D1 and D2) to convert an alternating current (AC) input into a direct current (DC) output. The circuit allows both halves of the AC waveform to contribute to the output.

**Hint:** Remember that in a full wave rectifier, both diodes conduct during different halves of the AC cycle.

### Step 2: Analyze the Input Waveform
The input to the full wave rectifier is a sinusoidal AC waveform. This waveform has both positive and negative halves. The positive half will allow diode D1 to conduct, while the negative half will allow diode D2 to conduct.

**Hint:** Identify which diode conducts during each half of the AC cycle.

### Step 3: Determine the Output Waveform
The output waveform of a full wave rectifier will consist of peaks corresponding to the conduction of each diode. During the positive half, D1 conducts and produces output peaks, while during the negative half, D2 conducts and produces its own output peaks.

**Hint:** Look for the peaks in the output waveform that correspond to the conduction of D2.

### Step 4: Identify Contributions from Diode D2
From the output waveform, we can identify the peaks that are associated with diode D2. In the output waveform, the peaks that occur during the negative half of the AC cycle are due to D2. Specifically, these are the second and fourth peaks of the output waveform.

**Hint:** Focus on the peaks that occur when the input waveform is in its negative half.

### Step 5: Conclusion
The contribution from diode D2 can be summarized as the output peaks that occur when D2 is conducting. In the context of the provided question, the peaks labeled B and D in the output waveform are the contributions from diode D2.

**Hint:** Make sure to clearly label the peaks in your analysis to avoid confusion.

### Final Answer
The contribution from the diode D2 is represented by the output peaks B and D.
