Homework Help: How to get the power that is dissipated

  1. Jun 24, 2010 #1
    1. The problem statement, all variables and given/known data

    Calculate the power dissipated by a resistor connected to a 1.5 V battery when R = 0.25 ohms.

    2. Relevant equations

    I = V/R

    3. The attempt at a solution

    I = V/R
    =1.5 V/0.25 ohms
    =6.0 A

    So, I know the current, but I don't know how to get the power that is dissipated. Can somebody please help me?
