Which of the following statements is not correct when a junction diode is in forward bias?
- A The width of depletion region decreases.
- B Free electrons on \(n\)-side will move towards the junction.
- C Holes on p-side move towards the junction.
- D Electron on \(n\)-side and holes on \(p\)-side will move away from junction.
Answer & Solution
Correct Answer
(D) Electron on \(n\)-side and holes on \(p\)-side will move away from junction.
Step-by-step Solution
Detailed explanation
In forward biasing both electrons and protons move towards the junction and hence the width of depletion region decreases.
