Probably a very simple question, but I'm not sure of the answer...
We have two batteries.
Scenario 1: The positive terminals of both batteries are connected together and the negative terminals are connected together. Little to no current flows, correct?
Scenario 2:
The positive terminal of battery A is connected to the negative terminal of battery B.
The positive terminal of battery B is connected to the negative terminal of battery A.
Now we have lots of current flowing, correct?
In scenario 1, apparently no circuit was completed, yet in scenario 2 we must have completed a circuit... Why? Did both batteries (of scenario 2) simultaneously become the sources and the loads? How would you calculate the current flow?
