I'm currently reading on my own on these topics for the first time in Fundamentals of Physics by HRW. Electric charge, electric fields, and Gauss' Law were 3 hard chapters, but manageable. In this chapter certain aspects aren't really clear to me at all, and there is more math than physical description (math isn't a problem, but there isn't enough of the latter to clarify the former), which is leaving me scratching my head and frustrated. Anyone know if these subjects are more fully fleshed out physically in another work or on a good website or video? I'm starting to see what others have said about Fundamentals cutting corners at times. Thanks.
