As we discussed in concept

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

 

 In forward biased PN junction diode P type is connected to positive terminal of battery and N type with negative terminal of the battery.


Option 1)

The N-end is connected to the positive terminal of the battery

 

This option is incorrect.

Option 2)

The P-end is connected to the positive terminal of the battery
 

This option is correct.

Option 3)

 The direction of current is from N-end to P-end in the diode
 

This option is incorrect.

Option 4)

The P-end is connected to the negative terminal of battery

This option is incorrect.
