Homework Statement
What i may ask may seem simple, but it is casuing me a lot of headaches. What is the effective potential difference across a resistor if it is connected to a parrallel connection of batteries. Let's quantify the variables. Battery one has an e.m.f. of 2 V while battery 2 has an e.m.f. of 6V. Resistor has a resistance of 7ohms.
Homework Equations
Kirchoff's spotential difference law
The Attempt at a Solution
Ok, according to kirchhoffs second law, for any closed loop, the algebraic sum of potential difference is 0. But for both closed loops, the potential difference across the resistor is different. So what really happens in this case? Will the potential difference across the resistor be 5V and the 2V battery does not release a current at all? Please help. Surely this is not the case.
