Q. Two $PN$-junctions can be connected in series by three different methods as shown in the figure. If the potential difference in the junctions in the same, then the correct connections will be
A) In the circuit (1) and (2)
B) In the circuit (2) and (3)
C) In the circuit (1) and (3)
D) Only in the circuit (1)
Explanation
(b) Because in case (1) N is connected with N. This is not a series combination of transistor
