Grade 8Electric Current

when two cella are connected in series the positive terminal of the first cell is connected to the negative terminal of the other cell and the point where the two cells are connected is the point where the negative terminal of the first cell is connected to the positive end of the other cell so ,how this increases the voltage and why the point where the two cells are connected are not neutralizing

The cells are connected in series and the circuit is closed henc if U apply KVL in the loop,
U would get,
E1 + E2 = iR
where R is the internal resistanc of the cells.
Hence the potential gets added hence increases the net potential of the circuit.
.
If one of the cell is connected in reverse then it would be neutralizing and only if both the cells have the same potential.
This needs to be clarified.
