Homework Statement [PLAIN]http://img600.imageshack.us/img600/7497/prob2.jpg Homework Equations I = V / R The Attempt at a Solution I tried to add the 3 voltages together but i didn't get a correct answer .. I guess I'm missing something that has to be with the parallel Circuit...

WoW .. you are really physics master! ^_^ we subtract of course! ^_^ R = V/I => R = (77-41) / 2 => R = 18 Ohms Thanks! ^_^ I really like this Forum! ^_^

imm .. yeah .. but the problem is .. this R experience two different voltages .. ! .. should I add them together or subtract or what should I do .. how do I know the true voltage on that resistor! :'( Thanks! ^_^

I got it .. ^_^ thanks! The correct answer for both ε1 and ε2 is: ε1 = 41v ε2 = 77v Great Job! ^_^ now how do we find the R on the top ..?? O_O

Great .. now I calculated the Voltage in each Resistor. V @ R1 = 9v V @ R2 = 32v V @ R 3 = 45v Now I need to add the sum of the voltage in the first loop and the second loop separately to get the 2 missing voltages .. so.. 9v + 32v + ε1 = 0 and 32v + 45v + ε2 = 0 is that correct ??

Thanks Master! That's really fast respond .. I'm impressed ^_^' well .. I try to use the formula again I = V / R .. but it's not working .. :( I heard that we need to use the Loop Method which I have no idea how to use! :( I wonder how do we fine the equivalent V for the circuit! ??
