The electrical resistance to the diffusion current in the depletion layer in a p-n junction is large due to the presence of
- A strong electric field
- B large number of charge carriers
- C electrons as charge carriers
- D holes as charge carriers
Answer & Solution
Correct Answer
(A) strong electric field
Step-by-step Solution
Detailed explanation
Diffusion current is caused by the movement of majority charge carriers (electrons from the n-side and holes from the p-side) crossing the junction. In the depletion layer, immobile positive and negative ions create a strong internal electric field directed from the n-side to…
