This is an excerpt from my book and I am not able to understand how could “V” be equal to Ε1- I1r1 as well as Ε2- I2r2.
I mean One battery could have emf of 50 volt and another just 5 volt. So, How could 50 be equal to 5? How could voltage across both the batteries be same?
And I also wonder if both the batteries were of equal emfs, would there be any current? Because that would be like two persons pushing with equal force but in opposite direction.
I mean electrons coming from two equal cells E1 and E2 in parallel combination (as in above figure), won’t they push against each other with equal force and hence no current should flow?
