Hello,
I'm wondering how to determine the value of the potential difference between two points (junctions specifically) in a circuit with 2 emfs. The junctions are points x and y in the circuit below.
I thought I could use the junction rule to determine the current at each junction, but I don't see how that can help me find the potential at those points as I don't see how I can find the resistance there. Then I tried using the loop rule on loop abcda to find the difference of the potentials (-(2A*5ohms)+28)-(-6A)(3ohms)=36V) but I'm not sure if that's correct, and this is a written assignment so I can't check if the answer is right or wrong.
Thanks
