## Main Question or Discussion Point

im taking circuit theory 2, which is all about ac circuits, but dont have enough money for a book

need a place to learn about how to calculate lead and lag based on the inductance and capacitance, nortons and thevinans and all that stuff but in the context of sinusoidal currents and voltages
