In a p-n junction under equilibrium:
- A Diffusion current dominates
- B Drift current dominates
- C No net current flows
- D Depending upon the semiconductor either diffusion current or drift current dominates.
Answer & Solution
Correct Answer
(C) No net current flows
Step-by-step Solution
Detailed explanation
At equilibrium, the diffusion current (caused by concentration differences) and the drift current (caused by the internal electric field) are equal and opposite. Because they perfectly cancel each other out, the net current is zero. C) No net current flows
