The system studied here (fig. 1) is a 2 coil setup embedded within a pure iron core. The setup can be treated like an Resistor and inductor system. A capacitor is added in parallel to reduce the impedance experienced by the system (fig. 2). A voltage source of 300 V at 1000 Hz is suppling the input to the system. By having a capacitor in parallel, there is a significant voltage drop experienced. The plot of the voltage reduction is shown in the fig. 3. The simulation was also ran for 200 ms with a 100 mF capacitor in parallel to ensure that steady state was achieved, as shown in fig. 4. I was wondering if someone could help me understand why this voltage drop occurs?

Hi, nCould you re-upload images for Fig.1 Fig.2 and Fig.3? They are not showing. Thanks.nn
