1. The problem statement, all variables and given/known data Calculate the Thevenin voltage Vt and the Thevenin resistance Rt. 2. Relevant equations V=(Vt*R)/(Rt+R) I=Vt/(Rt+R) 3. The attempt at a solution I'm thinkin that my R is 1 ohm but I can't figure out how to simply the rest of the resistors to get Rt. If I can get Rt, then I can solve for Vt. Is my thinking correct or am I completely off? I've attached a picture of the diagram. Any input would be great, thanx.
