find the value of $I_1,I_2,I_3$
• August 2nd 2010, 07:51 AM
Let $i_1$ be the current from E1 towards R1

and $i_2$ be the current from E2 towards R2

-----
Use Kirchhoff's loop law

We get

For the loop of potential E1

$6 = 3i_1 + 4(i_1 + i_2)$

For loop of E2

$12 = 12i_2 + 4(i_1 + i_2)$

--------
two equations and two unknowns....

$i_3 = i_1 + i_2$

I hope this one is clear than the one I told you there... :-)
