Two voltages are connected in series aiding,
Total voltage equal is to sum of two voltages.

Two voltages are connected in series opposition,
Total voltage is equal to difference of two voltages.

In series V=V1+V2;
V=6+9.
=15.

If the cells are connected in series, the voltage of the battery will be the sum of the cell voltages. For example, a 12 volt car battery contains six 2-volt cells connected in series.

Some vehicles, such as trucks, have two 12 volt batteries in series to feed the 24 volt system.

Series connection will be not same, do to voltage drop.

Yes you are right.

But without indicating polarity of cell we can't say adding or not.

Aiding means helping, so the addition of voltages.

From the same transformer which has a secondary output 6/0/6v, if I rectify to get two 6v dc voltage than I make these two different voltages adding in series, will the total voltage be 12v, and can this be applied in practical?
