In the depletion layer of a reverse biased p-n junction, the :
- A potential is zero
- B potential is maximum
- C drift current is zero
- D electric field is zero
Answer & Solution
Correct Answer
(B) potential is maximum
Step-by-step Solution
Detailed explanation
The potential increases across the depletion layer from the p-side to the n-side, reaching its maximum value at the n-side edge of the depletion layer. In the depletion layer of a reverse biased p-n junction, the potential is maximum.
