0.1A discrepancy when summing currents in parallel circuit

[Mark Nussbaum]

Homework Statement

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...

With an app like DocScanHD cheap and there are free versions I think you might get this readable before the Americans , majority of members, wake up.

Imgur is another way to post pics. Free app for phones, and it can generate the BBCode to link to the pic.

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.
