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
increases the number of donors on the n-side
Explanation
Solution
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.
