Application of a forward bias to a p-n junction

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

Tardigrade Admin · Accepted Answer

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.

Q. Application of a forward bias to a p−n junction

increases the number of donors on the n-side

increases the electric field in the depletion zone

increases the potential difference across the depletion zone

widens the depletion zone

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.

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

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.
