    image In the given circuits (a), (b) and (c), the potential drop across the two p-n junctions are equal in :

    (A)Both circuits
    (a) and
    (c)
    (B)Circuit
    (a) only
    (C)Circuit
    (b) only
    (D)Circuit
    (c) only
    digAnsr:   A
    Ans : 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.
