QNEET-2022-Ph-459: NEET 2022 Physics - Class 12 NEET-2022-Ph-459 Solution: In the given circuits (a) (b) and (c) the potential drop across …
In the given circuits (a) (b) and (c) the potential drop across the two p-n junctions are equal in Circuit (a) only Circuit (b) only Circuit (c) only Both circuits (a) and (c)
Multiple Choice Options
- A Circuit (a) only
- B Circuit (b) only
- C Circuit (c) only
- D Both circuits (a) and (c)
Step-by-Step Verified Solution
Potential drops across the p-n junctions will be same if either both junctions are forward biased or both junction are reverse biased.
In figure (a) and (c), both junctions are forward biased therefore both have same potential.
In figure (b) first junction is forward biased and second junction is reverse biased, so both junctions have different potential difference.
