A) circuit 1 and circuit 2
B) circuit 2 and circuit 3
C) circuit 3 and circuit 1
D) circuit 1 only
Correct Answer: B
Solution :
In circuit 1-One diode is forward biased while other is reverse biased. So, they offer different resistance and hence potential difference would be different, across the two diodes. In circuit 2-Both the diodes are forward biased, so same resistance and hence same potential difference across the two diodes. In circuit 3-Both the diodes are reverse biased, so resistances are same (but very high) and hence same pontential difference across the two diodes.You need to login to perform this action.
