1. The problem statement, all variables and given/known data Calculate the power Pa and Pb supplied by batteries A and B respectively (see attached diagram) 2. Relevant equations P=iV, P=i^2R, and P=V^2/R 3. The attempt at a solution I already found i1, i2 and i3 to be 5.714, 1.143, and -4.571 respectively. I am confused over the difference between P=iV, P=i^2R, and P=V^2/R so I am not sure what to do next.
