Finding Power in watt with a real battery

  1. Apr 14, 2010 #1
    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?

    The images shows that the battery has 10 ohm and 1.5V.

    It is due tonight and I am lost :( please help!

    oh and I know P=I*V=V^2/R=RI^2
