Question:
Application of a forward bias to a p-n junction
Application of a forward bias to a p-n junction
Updated On: Jun 17, 2022
- 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
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
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.
In this condition, more number of electrons enter in n-side from battery thereby increasing the number of donors on n-side.

Concepts Used:
Semiconductors
Semiconductors are a crystalline solid materials, whose electrical conductivity lies between a conductor and an insulator. Semiconductors are mainly used in the manufacturing of electronic devices like capacitors, transistors, diodes, Integrated circuits, etc.
Properties of Semiconductor:
- Semiconductor acts like an insulator at Zero Kelvin. On increasing the temperature, it works as a conductor.
- Due to their exceptional electrical properties, semiconductors can be modified by doping to make semiconductor devices suitable for energy conversion, switches, and amplifiers.
- Lesser power losses.
Uses of Semiconductor:
- Semiconductors are widely used in manufacturing electronics devices like transistors, diodes, sensors, integrated circuits.
- Semiconductors are widely used in all electronic devices, like mobile phones, digital cameras, communication devices, trains, ATMs, etc.
