## Homework Statement

Find I1 , I2 and I3

## Homework Equations

I = E / R

I3 = I1 - I2

## The Attempt at a Solution

its the trouble with parallel different emf . I know a formula how to combine them into one but it needs inner resistance . i dont know how to do it with the ideal circuit . The combine emf will go to bigger emf or the sum of them ? and how to find the current then ? please help :(
