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 

R  \rightarrow \infty Reverse

 

In this situation 

D_{2} is in reverse bias

so no current will pass through

D_{2} & (75\Omega ) Resistance.

I=\frac{V}{R_{net}}=\frac{6}{100+50+150}=\frac{6}{300}

I=0.002 A
