Question
Two identical p-n junctions are connected in series in three different ways as shown below to a battery. The potential drop across the p-n junctions are equal in
- Circuits 2 and 3
- Circuits 1 and 2
- Circuits 1 and 3
- None of the circuit
The correct answer is: Circuits 2 and 3
In circuit 2, each p-njunction is reverse biased, some current will flow giving equal potential difference across each p-njunction diode. In circuit 3, each p-njunction is forward biased, hence same current flows, giving same potential difference across p-njunctions.
