# The reverse biasing in a PN junction diode Option 1) Decreases the potential barrier Option 2) Increases the potential barrier Option 3) Increases the number of minority charge carriers Option 4) Increases the number of majority charge carriers

As we learnt in

P -N junction as diode -

It is a one way device. It offers a low resistance when forward biased and high resistance when reverse biased.

- wherein

R = 0, Forward

$\rightarrow \infty$ Reverse

Do to reverse biasing potential barrier increases but it has no effect on number of charge carrier.

Option 1)

Decreases the potential barrier

Incorrect

Option 2)

Increases the potential barrier

Correct

Option 3)

Increases the number of minority charge carriers

Incorrect

Option 4)

Increases the number of majority charge carriers

Incorrect
