A `p-n` junction diode is reverse biased. Then

Options

A. no current flows
B. the depletion region is increased
C. the depletion region is reduced
D. the height of the potential barrier is reduced

Answer

B

Explanation

In reverse biasing, the applied voltage V on the n-side is positive and is negative on the p-side. The applied bias V. and the barrier potential `V_(B)` aer in potential `V+V_(B)` As a result the junction width will increase, the higher junction potential restricts the flow of majority carriers. So reverse bias current will be due to the ninority carriers only.
