Question

Application of a forward bias to a $p-n$ junction

• A. increases the number of donors on the n-side
• B. increases the electric field in the depletion zone
• C. increases the potential difference across the depletion zone
• D. widens the depletion zone

Answer 1

Answer: (A)

When p-side of junction diode is connected to positive of battery and n-side to the negative, then junction diode is forward biased.
In this condition, more number of electrons enter in n-side from battery thereby increasing the number of donors on n-side.
