Once you make sure your calculation is correct for both currents, You can write a very simple program using the equations either in spreadsheet, or Python, Java or C++ whichever you feel comfortable so that you can get the currents I, and I, prediction for different voltages and resistances. If you are not familiar to program, you can use the following program for the current prediction. Go to online python compiler: http:://www.onlinegdb.com/online_python_compiler Delete everything and copy and paste the following program. When you run the program, program provides you l, and I, for the given values (look at the figure below). You can change Voltages supplied and/or resistances to predict the currents for those voltages and resistance in the circuit we worked on
