1. The problem statement, all variables and given/known data (a) Suppose that R_1 = 6 ohms and R_2 = 3 ohms. Find the current i and the voltage v. See the diagram in the picture. http://img291.imageshack.us/img291/7638/picturewr3.th.jpg [Broken] 2. Relevant equations Kirchhoff's laws and Ohm's law 3. The attempt at a solution I got v=12V and i=1A However, I do not think that this is correct since a positive value for i means the voltage source is absorbing energy instead of supplying it, which does not make sense.
