+// Given data
+I1=0.5*10^-3; // Diode current in mA at 340mV
+I2=15*10^-3; // Diode current in mA at 465mV
+kb_T=5*10^-3; // Constant in mV
+
+// Calculation
+// After simplifying the current equation we get an expression for eta
+eta=5/(2.303*log10(30));
+
+printf("Ideality factor = %0.2f",eta);
+
+// Result
+// Ideality factor = 1.47
