2.2. Introduction

The simulation of the electric circuit in this exercise takes three dimensions, each of which shows a unique result. The methods are simulation with ODE, Powersim toolbox and Simulink and State Space block (Brian, 27). The output demonstrates the variation of the electric properties against time.

2.4. Comparison of the three Results

The first simulation shows three lines of voltage for Vx1, Vx2 and vx3. These are the three variables representing the voltage at different time and at different currents. Vx3 has the greatest amplitude followed by vx1 then finally vx2. The second simulation shows non linear relationship between the voltage and the time (Shailendra, 54) and (Khaled 38). The bode plottting shows almost constant boud against the time variable then a decline from the midle to the end. Simulation 3 shows results in separate plotting for y1 and y2 in which the amplitude of the voltages are higher that in a separate y1 plotting.
