1. The problem statement, all variables and given/known data See attachment for the question and the picture 2. Relevant equations Pe= E x Is Is = V/R 3. The attempt at a solution I figured that in order to find the power delivered by the source, I would have to use the equation: Pe= E x Is. E is already given to me.. 60. That means I just have to find Is. I used the formula Is= V/R and applied it to each resistor to find the current. Here is what I got: I1= 12A I2= 30 A I3= 7.5 A I4= 3 A I5= 5 A I added these values up to find Is and got 57.5 A. Now I apply the formula Pe= E x Is (Pe= 60 x 57.5) and got 3450 Watts for the power delivered by the battery. However.. The correct answer is 1.56 kW Am I using the wrong formula completely? Where did I go wrong? Thanks!
