**edit** This problem has been solved. For the circuit shown in the figure, find a differential equation the relates the input current i1(t) to the output voltage e0(t). Note that you cannot take a KVL across a current source because you cannot figure out the voltage drop across it. the circuit: http://www.flickr.com/photos/70948910@N08/6412941773 my work so far: http://www.flickr.com/photos/70948910@N08/6413318181/ Am I on the right track? We never had any problems with a current source during the lectures, and I don't know if I can set the voltages of parallel branches equal like that. Any ideas will be greatly appreciated!! It has been very tough getting in touch with my professor over Thanksgiving break and this assignment is due tomorrow.
