// To Compute alpha, beta and Emitter Current // Basic Electronics // By Debashis De // First Edition, 2010 // Dorling Kindersley Pvt. Ltd. India // Example 4-5 in page 209 clear; clc; close; // Given Data Ib=50*10^-6; // Base Current in mu-A Ic=5*10^-3; // Collector Current in mA // Calculations Ie=Ic+Ib; beta_bjt=Ic/Ib; alpha=Ic/Ie; printf("(a)The value of the Emitter Current is %0.2e A \n",Ie); printf("(b)The value of beta gain of the BJT is %0.0f \n",beta_bjt); printf("(c)The value of alpha gain of the BJT is %0.3f \n",alpha); // Results // (a) The value of the Emitter Current is 5.05 mA // (b) The value of the beta gain of the BJT is 100 // (c) The value of the alpha gain of the BJT is 0.990
