1. The problem statement, all variables and given/known data Hey everyone. I might be overthinking this one, but I thought I'd post it. (sorry for the crappy MS Paint sketch!) I need to find the current through R3 2. Relevant equations V=IR [itex]\Sigma[/itex]V=0 (around a closed loop) [itex]\Sigma[/itex]I=0 (going into a junction) 3. The attempt at a solution Well my original idea was to write out the value of an equivalent resistor for the 3 resistors in parallel, then use that to find the voltage drop (since it's the same across all 3). However since the values are all different, the algebra got messy pretty quickly, and I thought there would be a much simpler solution to the problem. I'm just a bit thrown off by the constant-current source instead of emf. Thank you for any and all help!
