Physics Question on P-N Junction
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
raises the potential barrier
Explanation
Solution
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.
