1. The problem statement, all variables and given/known data For the circuit shown, find the power dissipated by the 10.0 ohm resistor. (as attached) 2. Relevant equations P=IV=I2R=V2R V=IR 3. The attempt at a solution I really don't know where to start with this. I'm basically tied up in the fact that there are three different sources of voltage. Am I to add the series/parallel resistances up for the whole circuit? I think I have to find current I in order to solve this but i'm really confused.
