Question
Two identical 
junction may be connected in series with a battery in three ways as shown in the adjoining figure. The potential drop across the junctions are equal in
- Circuit 1 and circuit 2
- Circuit 2 and circuit 3
- Circuit 3 and circuit 1
- Circuit 1 only
The correct answer is: Circuit 2 and circuit 3
In circuit 1, 
is connected with , which is not a series combination of junction. In circuit 2, each junction is forward biased, hence same current flows, giving same potential difference across junction. In circuit 2, each junction is reverse biased, same leakage current will flow, giving equal potential difference across each junction diode.
