Basically, find Vab
Is this correct -- note: please tell me that my methodology is sound; DO NOT GIVE ME A NUMERICAL ANSWER.
The problem asks for VAB. What's weird to me is that there is a potential across two terminals? (The weird part is: the terminals are connected to another voltage source!)
I used KVL... and I'm fairly accurate that my calculation is correct. However, I am confused with finding the actual VAB. Can I simply apply Ohm's law, and "lump" all of the resistors into one resistor (composition?) Would VAB be equivalent to the sum of all the voltages (taking polarities into account)?
