Hi Lyle,
Good you have already made strides to understand the basics. To advance further you will likely need to start doing some math exercises on things such as RC time constants, some basic trig for better understanding resonance, phasing, and power factors. Thevenin theorem is very useful for simplifying more complex circuits. Not sure what text books cover all these topics nowadays. But shouldn't be hard to search them out. My 2 cents.
