P-N Junction Diode Problem HELP

[truettct]

Homework Statement

A pn junction diode has saturation current Is= 1e-12 A. What is the current through this diode if a positive voltage 0.68 V is applied to it? (Unit: A)

Homework Equations

I=I_s(e_{(V^d)/(Vt))-1)}

The Attempt at a Solution

I don't even know where to begin, but i just need a good explanation and how to solve this problem to help me visually learn it. I can't find much info on the web about this problem.

Thanks

You have the value of I_s and V_d = 0.68V. The voltage V_T is dependent of temperature. It is 26mV at 300 K.
Do the math.
