Helo,
I am in an electronic course and we just started studying diodes. I am stuck on the following problem:
Place a 100 ohm resistance in series with a diode, and plot current versus voltage across the series combination.
I am also given the following values for the diode:
n = 1, Is = 10^-14A, Vt = 26mVI am trying to come up with an expression for current. I am using the following:
iD = Is * exp(vD/(n*Vt)) ... approximation of the current through the diode.
and
Vr = iR for the voltage drop across the resistor
Then, the total voltage drop is:
Vtot = vD + Vr
I am then trying to solve for current, but I can't get it on its own. Can some one please help me. I have attached a picture of the original problem statement. Thank you very. much!
