RE R - 592 151 V2 R-112 13 Figure 1 Circuit with two voltage sources R2-612 RaxR R = R + Rs+R2 R, -0.602 R3-40 Figure 2 Components of Rx PART 2: Calculations of Current and voltage (40 marks) Create, declare and define functions to calculate voltage and current Circuit diagram is shown in figures 1 and 2. Use functions to return the magnitude of current ix and ly in order to calculate va.

PART 3: TESTING MODELS (35 marks) a) Design test data (e.g. values for the variables shown in figures 1 and 2) that should be listed in a table. Testing strategy needs to be explained including assumptions made for the process. b) Write a main program to invoke the functions developed in Part 1 to test the correctness of calculated coefficients for the standard equations. c) Test the developed program that can display the results of ix, iy, and v2, on the screen or save them into a file. d) When the processing is complete, offer the user the option of displaying the results on the screen or writing the results to a user specified data file. Credit will be awarded for a solution that allows the user to make a choice. It is acceptable, if the input values, such as v1, v2, R1, R2, R3, Ry and Rz are not by a prompt but by a default value. However,
