// find power dissipation
// Electronic Principles
// By Albert Malvino , David Bates
// Seventh Edition
// The McGraw-Hill Companies
// Example 6-11, page 211
clear;clc; close;
// Given data
Vce=10;// collector-emmiter voltage in volts
Ic=20*10^-3;// collector-current in amperes
T=25;// ambient temperature
P=625*10^-3;// power rating in watts at 25 degree celcius
// Calculations
Pd=Vce*Ic;// power dissipation in watts
disp("watts",Pd,"dissipated power=")
// Result
// As power dissipation is less than rated power at ambient temperature,transistor(2N3904) is safe
