1. The problem statement, all variables and given/known data I must find the resistance of a diode inside the piecewise model using the diode law equation. I am given variables VD = .75V, Is = 5*10^-13 A, and VT = .026 A. n = 1 2. Relevant equations The Diode Law equation: ID = IS(e(VD/nVT) - 1) 3. The attempt at a solution We were told that to find the resistance, we are to find the derivative of this equation to find the conductance, and then the inverse of this would be the resistance. I'm not sure what to derive with respect to or if even this explanation is correct. Can anyone help explain how to find resistance using this equation?
