Answer Posted / ashish sharma
We know that electrons flow from negative to positive directions and the current flow the opposite direction. In the batteries their are two polarity one is pos.(+) and another is neg.(-) so that when two batteries connected in the series then due to same directions of flow current the, voltage get added.
In other case when two batteries connected in the parallel than the same polarity of the charges so that repulsion get occured hence the voltage get subtracted.
