Question

Consider the following circuit with two identical Si diodes. The input ac voltage waveform has the peak voltage \( V_P = 2V \), as shown. The voltage waveform across PQ will be represented by: 

Hint:

In circuits with diodes, the output waveform is often half-wave rectified unless a more complex configuration is used.

Answer 1

Step 1: Understanding the circuit.
The circuit consists of two diodes arranged in a manner that will rectify the alternating current (AC) input voltage. The voltage waveform across the diodes will be modified based on how the diodes allow current to pass. The diodes conduct during one half of the AC cycle, blocking current during the opposite half. This produces a half-wave rectified output across PQ.
Step 2: Conclusion.
The correct answer is option (B) because the voltage waveform will be half-wave rectified due to the diodes’ behavior.
