So i have a midterm tomorrow in E&M and i'm not well prepared at all. The whole class is pretty much already prepared to fail... so i'm not alone in that at least. Basically, i have one more day (tomorrow) to study, so i best make the best of it. We get to bring index card "cheat sheets" that have any formulas we think will be handy, so i won't waste time memorizing that stuff. Basically, i was hoping you all could point me in the most efficient directions and tell me what are probably the most important concepts and ideas, and will likely be tested. The topics we're covering are: capacitors and capacitance current -Ohms law Resistors batteries wheatstone bridge.... kirkoff rules? RC circuits AC power magnetism? (my notes have gone that far, but i went to class last week and we weren't any where near magnetism, so i dunno if that'd be on the test) So ya, hopefully you can just tell me what you think the most important stuff to study would be, and then i can do that. Thank you.
