In the working of photodiode, the reverse current depends on
- A concentration of majority carriers.
- B concentration of minority carriers.
- C applied voltage.
- D recombination of holes and electrons.
Answer & Solution
Correct Answer
(B) concentration of minority carriers.
Step-by-step Solution
Detailed explanation
The reverse current in a photodiode depends significantly on the concentration of minority carriers (electrons in the p-region and holes in the \(n\)-region). When light strikes the photodiode, it generates electron-hole pairs, and these minority carriers contribute to the reverse current when they are swept across the junction by the electric field.
