In the circuit shown here the conventional current direction is from V2 to V1 and is equal to 3 Amp. I understand the theory. But, if I make this circuit with two batteries, according to the schematic the current(positive charge) leaves a positive side of one battery and goes through the positive side of the second battery.
So my question is, if I actually make this circuit with two batteries, does it mean that a battery (V1 here) accepts current to its positive side and send current from its negative side? How is that possible? How would the current circulates?
