I found it extremely helpful to first study the basic physics of electromagnetism in some depth rather than jump straight to electric circuits and components. Any undergrad physics textbook that eventually teaches Maxwell's equations will do. For video format, Walter Lewin's 802.x MIT lectures are freely available online. (I think there's some debate over whether he got a particular example involving Kirchoff's Law quite right. Not sure what other lecturers are good, but they are around if you find Lewin not to your liking.)
