As we have learned

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 one case 

NO current will pass through D_2

I = 2/5 A = 0.4 A 

In second case : no current will pass through D_1

I = 2/10 = 0.2 A 

 

 


Option 1)

0.2 A and 0.1 A
 

Option 2)

0.4 A and 0.2 A

Option 3)

0.1 A and 0.2 A

 

Option 4)

 0.2 A and 0.4 A
