Currently taking a circuits course as a upper level physics elective and I am having difficulties in this course. In particular we have done RL, RC, and RLC circuits in parallel using second order differential equations in class. I can follow in class lectures well however once I get home to try and study or attempt the homework I find that I cannot remember anything at all about the weeks notes. I can do simple problems but if its a loop equation with a current source and RL or RC circuit then I just freeze up and don't know what to do. As such I'm looking for help, as no textbook is supplied with this course and the professor has already shown her great dislike of me over the current semester as well as in previous years.
