Resistance in case of non Ohmic current voltage relation.

Mitadru Banik

A non Ohmic relation of current and voltage is I=α(exp(eV/kT)-1). Where α,K,T,e are constant. What will be the incremental resistance?

My question is if it don't follow the Ohmic equation then how it possible to find the resistance?
