Homework Help: physics-series and parellel circuits

Posted by Dav e on Sunday, May 20, 2012 at 5:01pm.

I'll try to explain the schmatic drawing...
a 120V battery, total of 12A, leads into a 8ohm resistor (R1), then breaks off into two parallel lines, R2 and R3. the resistance is unknown in R2, and in R3 the resistance is 3 ohms. I need to find the Amperage in R1,R2 and R3 as well as the resistance (ohms) on R2
I hope this explains it... HELP
