Can somebody explain why the magnetizing current starts at a negative value?
The highlighted part below kind of gives me a hard time to comprehend. Does this mean that the voltage across the capacitor is changing from one value to another instantly when S2 closes? I was taught that capacitor voltages can't instantaneously change. Also what does having large value of this cap have to do with the voltage being constant? Thanks!
