1. I have a question regarding the treatment of voltage sources in Mesh Analysis by inspection. I hope this is the correct place to post. In my course textbook (Fundamentals of Electric Circuits 4e p. 101) it says that the voltage is the algebraic sum taken clockwise of all independent voltage sources in the related mesh. Yet in an example problem they do not stay consistent with this. I found the same example problem in some lecture slides online: So I'm left wondering: - Does the example have an error and they actually meant to do clock wise drop is positive? My textbook makes no mention of treating a drop as positive for Mesh analysis by inspection. - If it isn't an error, and they did CW with rise positive, is that any different than just taking it CCW with drop being positive?
