1. The problem statement, all variables and given/known data http://img638.imageshack.us/img638/2416/64523221.jpg [Broken] 2. Relevant equations 3. The attempt at a solution My approach at this problem is using the voltage division law: I first need to find the voltage at the 12 ohm, this can be done by the following using voltage division law. Vb = (0.04 * 13)/ 41 Va = (0.04 * 28)/ 41 then we subtract the two, is this true?
