It sounds like you're eager to learn so I think you might get something useful out of this book ... if you're interested in fully understanding how LRC circuits work you first need to know some calculus. A good book that has nothing to do with electronics but can give you a good introduction to calculus without the boring/ confusing nature of a textbook is "Calculus made easy" by Silvanus P. Thompson. I wish I head read this book when I was in high school. It's a light but thorough introduction to calculus, which will ultimately by the basis of almost everything you do in electronics if you decide to take it further and become an engineer. Good luck, it's nice to see someone that's interested in reading and learning without being forced to do it.
