In the given circuits (a), (b) and (c), the potential drop across the two p-n junctions are equal in : 1. Both circuits (a) and (c) 2. Circuit (a) only 3. Circuit (b) only 4. Circuit (c) only

Answer: 1. Both circuits (a) and (c) Two diodes in series with a battery see the same current, so their voltage drops are equal when both are in the same bias condition (both forward or both reverse). (a) Both are P-N in the same direction: both forward or both reverse, so equal drops. (b) One is P-N and the other N-P: one forward and one reverse, so unequal. The reverse diode takes almost the full voltage. (c) Both N-P in the same direction: same bias, equal drops. So (a) and (c): option (1).

Answer: 1. Both circuits (a) and (c)

Two diodes in series with a battery see the same current, so their voltage drops are equal when both are in the same bias condition (both forward or both reverse).

(a) Both are P-N in the same direction: both forward or both reverse, so equal drops.
(b) One is P-N and the other N-P: one forward and one reverse, so unequal. The reverse diode takes almost the full voltage.
(c) Both N-P in the same direction: same bias, equal drops.

So (a) and (c): option (1).
