clear; clc; close;
// Given data
V_T=0.0343; // Thermal voltage at 398K in V
eta=1; // Constant for Ge
// Calculation
// Final expression for r derived after differentiating w.r.t V
r1=((35*10^-6)/(34.3*10^-3))*exp(5.83);
A1=1/r1;
r2=3.185*10^-6
A2=1/r2;
printf("(a)Dynamic resistance in forward direction = %0.3f ohm\n",A1);
printf("(b)Dynamic resistance in reverse direction = %0.3e ohm",A2);
// Result
// (a) Resistance in forward direction = 2.879 ohm
// (b) Resistance in reverse direction = 0.314 Mohm
