When you are using Kirchhoff's voltage law and you come across a current source, what are you supposed to include that as? Pretending that it is an ideal current source, there will be no resistance and thus no voltage drop. So, do you just ignore it in the voltage equation? (Ex: V1+V2+V3=0) Because of the fact that you can re-arrange a resistor and voltage source in parallel to a current source and resistor in series, I'm a little confused. Any help much appreciated.
