[QUOTE="vanhees71, post: 6047116, member: 260864"] Well the signs you understand best when going back to the first principles the circuit equations derive from. For induction it's of course Faraday's law, and there (as with all things having to do with curls and rotation) the right-hand rule is your friend. Here are some notes from a lecture, I've given to Texan engineering students some time ago. Maybe they are of some use (although in my very bad handwriting ;-(): [URL]https://th.physik.uni-frankfurt.de/~hees/physics208/phys208-notes-III.pdf[/URL] The part on induction you starts on page 106. The course website with some more material is here: [URL]https://th.physik.uni-frankfurt.de/~hees/physics208.html[/URL] [/QUOTE]
