Hello, for this question I get C, because I find the current in each loop by finding total resistance and dividing current by that, then multiply by two as there are two of these loops but it is the wrong answer.
How would I getB as the answer?![Name: 03463943-6E4A-4EF2-A450-9FED19DE13EF.jpg.jpeg

So 1.5 = 0.8I + 2.4I
Solve and you get I = 0.46875 so it's B

The resistance of the battery combination is 0.8 as they're in parallel.
So 1.5 = 0.8I + 2.4I
Solve and you get I = 0.46875 so it's B

because kirchoffs second law it goes through one battery at a time. emf in is equal to V out in closed loop,

But non of the current from the first battery will go through that second battery will it because the currents would oppose eachother?
