Homework Equations


V=IR
parallel resistance.

The Attempt at a Solution


All elements are in parallel (teacher confirmed this in explanation to the class). Beginning placing labels for nodes to the right of R1, A, B, C, D, and E (ending before R4) and redrawing it as the teacher showed to get us started...

Once I add the currents together in the original equation I end up with .1A left over...
(sorry about low quality don't know how to get it to a webpage.)

Mark Nussbaum, are you still working on this? You know the current from the .5 Vx source and you know the current through R4 (it's the same as I5); do you see how those two allow you to calculate I4?
 
Yeah I realized it after it was due but now I'll know for next time.
