# The current in a diode is given as a function of voltage

Q- The current I as a function of voltage V for a certain diode is given by

I(V)=I_0 (e^(eV/kT) - 1)

Here k is Boltzmann's constant, e is the charge on an electron (magnitude), and T is the absolute temperature. Let at room temperature (t = 20 degree C), I_0 = 1.5 × 10^(-9)A.

(A) What is the resistance of the diode for V = 0.51 V?

(B) What is the resistance of the diode for V = 0.61 V?
