MCQ
Two $P N$-junctions can be connected in series by three different methods as shown in the figure. If the potential difference in the junctions is the same, then the correct connections will beImage
  • A
    In the circuit (1) and (2)
  • ✓
    In the circuit (2) and (3)
  • C
    In the circuit (1) and (3)
  • D
    Only in the circuit (1)
✓

Answer

Correct option: B.
In the circuit (2) and (3)
Because in case (1) $\mathrm{N}$ is connected with $\mathrm{N}$. This is not a series combination of transistor.
