The built-in potential of a p-n junction diode is \(0.7 \mathrm{~V}\). If the diode is forward biased and the applied voltage is 0.3 \(\mathrm{V}\), the effective barrier height is
- A \(0.7 \mathrm{~V}\)
- B \(0.3 \mathrm{~V}\)
- C \(0.4 \mathrm{~V}\)
- D \(1 \mathrm{~V}\)
Answer & Solution
Correct Answer
(C) \(0.4 \mathrm{~V}\)
Step-by-step Solution
Detailed explanation
\(V_{eff} = V_{bi} - V_{applied}\) \(V_{eff} = 0.7 \mathrm{~V} - 0.3 \mathrm{~V}\) \(V_{eff} = 0.4 \mathrm{~V}\)
