1. The problem statement, all variables and given/known data calculate the power dissipated by a resistor R connected to the battery when R = 2.4 ohm. 2. Relevant equations I=V/R 3. The attempt at a solution I found A of battery that given and put R value given to find P, however I cannot get a right answer. What did I wrong? http://session.masteringphysics.com/problemAsset/1021126/12/jfk.Figure.23.P47.new.jpg The images shows that the battery has 10 ohm and 1.5V. It is due tonight and I am lost :( please help!
