The reverse saturation current in a diode can be calculated using Ohm's Law:

I%20%3D%20%5Cfrac%7BV%7D%7BR%7D

where

I

is the current,

V

is the applied reverse bias voltage, and

R

is the resistance of the diode. Given:

V%20%3D%208%20%5C%2C%20%5Ctext%7BV%7D%2C%20%5Cquad%20R%20%3D%204%20%5Ctimes%2010%5E7%20%5C%2C%20%5COmega

Substitute the values into the equation:

I%20%3D%20%5Cfrac%7B8%7D%7B4%20%5Ctimes%2010%5E7%7D%20%3D%200.2%20%5Ctimes%2010%5E%7B-6%7D%20%5C%2C%20%5Ctext%7BA%7D%20%3D%200.2%20%5C%2C%20%5Cmu%20A

Thus, the reverse saturation current is

0.2%20%5C%2C%20%5Cmu%20A

. Therefore, the correct answer is

%5Cboxed%7B0.2%20%5C%2C%20%5Cmu%20A%7D
