MCQ
In the given circuits $(a)$,$(b)$ and $(c)$, the potential drop across the two p-n junctions are equal in:
  • A
    Circuit $(b)$ only
  • B
    Circuit $(c)$ only
  • Both circuits $(a)$ and $(c)$
  • D
    Circuit $(a)$ only

Answer

Correct option: C.
Both circuits $(a)$ and $(c)$
c
In $(a)$ $\&$ $(c)$ circuits, both the junctions are in same biasing conditions so offers equal resistances.

Since both are in series, therefore equal potential will drop across the junction.
