1. The problem statement, all variables and given/known data Check the Picture 2. Relevant equations 3. The attempt at a solution I've never dealt with a three-cell circuit before. For calculating the current, I tried doing Kirschoff's Voltage Law, all I kept getting was that I1 = negative I2. I tried taking the current as coming out of the 2 voltage cell, but now i'm starting to doubt myself. However, taking it from the other cells doesn't seem to do anything else. I'm not quite sure how to solve b, or c without a. Any help? Thanks!
