## Homework Statement

http://tinypic.com/r/e8v1ad/6

^^ that is a photo of the circuit

## Homework Equations

P = I*V , but i dont understand how to do it with two loops and two batteries like in this photo.

## The Attempt at a Solution

I have calculated I1 to be .9, I 2 to be .15 and I3 to be .75.

On the very left of the photo is a 15 V battery and the resistor on the bottom that you cant really read is 100 olms.

The other battery (i put a square around the batterys) is 9 V.

Just kinda confused on how to put them together. thnks for your help
