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?

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 oC), I0 = 1.5 × 10 -9A.
What is the resistance of the diode for V = 0.51V?
What is the resistance of the diode for V = 0.61V?
Solution:
The current is not directly proportional to the potential difference and thus the conductor is not following Ohm's law and thus called a non-Ohmic conductor.
According to Ohm's law if the physical conditions of a conductor remain ...
