1. The problem statement, all variables and given/known data Hi, I need to produce a linearized equation of the following, I = D. V. exp(-V/B) eq(1) I is the current V is the voltage D is a constant B is a constant Data was collected in an experiment designed to investigate the characteristics of a tunnel diode. I didn't do the experiment myself, I just have to find the linearized form of eq(1) and determine the constants D and B. I have a set of I values and a set of V values given to me to allow me to calculate the constants. 2. Relevant equations I = D. V. exp(-V/B) eq(1) 3. The attempt at a solution The problem I am having is the V term before the exponential term. Taking logs of both sides, Ln(I) = Ln(D) + Ln(V) - V/B eq(2) I'm going to use excel to determine B and D. I'm just not sure how to graph it. If there was no V term before the exponential term then it would be, Ln(I) = Ln(D) - V/B eq(3) and i could simply graph Ln(I) vs V, and 1/B would be my gradient and Ln(D) would be my y-intercept. I can't do this for eq(2) though because of the Ln(V) term. If I graphed Ln(I) vs Ln(v) - V, i can't determine B. I just can't seem to find a way to do it. I'm sure there's a simply way. I just need to work out how to bring the V's together. Any help would be greatly appreciated.
