Question

Reverse bias applied to a p-n junction diode

• A. lowers the potential barrier
• B. decreases the majority charge carriers
• C. raises the potential barrier
• D. change the mass of p-n junction diode

Answer 1

Answer: (C)

In reverse bias applied to a p-n junction diode raises the potential barrier because p-type material conncted to the negative terminal and pullesthe holes away from the junction.
Similarly n-type material connected to positive terminal and pulles the electrons. Therefore the depletion region widens.
