Reverse bias applied to a junction diode ……

Options

A. increase minority carrier current.
B. lowers the potential barrier.
C. raises the potential barrier.
D. increases majority carrier current.

Answer

C

Explanation

raises the potential barrier.
In reverse bias, at p-n junction flow is not by to majority carriers, but flow due to minority carriers. (If battery.s volt is high). As the size of the deplection barrier increases, the potential barrier also increases.
