In the case of **series aiding**, cells are connected one in front of another with the positive terminal connecting to the negative terminal of the other in a line.
In this configuration the same current flows through all the cells, it is not accumulative. We represent this as follows:
In this configuration the same current flows through all the cells; it is not cumulative. We represent this as follows:
$$
I_{T} = I_{1} = I_{2} = I_{3}
$$
However the voltage is accumulative: it is the _sum_ of the individual cell voltages, represented below as [electrical field](/Electronics/Physics_of_electricity/Voltage.md#distinguishing-voltage-from-electric-field):
However the voltage is cumulative: it is the _sum_ of the individual cell voltages, represented below as [electrical field](/Electronics/Physics_of_electricity/Voltage.md#distinguishing-voltage-from-electric-field):
$$
E_{T} = E_{1} + E_{2} + E_{3} \\
$$
Hence why series connections increase voltage but keep current constant.
Thus series connections increase voltage but keep current constant.

In parallel connections all positive terminals are connected to each other and all negative terminals are connected to each other.
This time the voltage is the same of each individual cell but the current is the sum of the individual cell currents. So the voltage is constant but the current is accumulative:

### Series-parrallel
If we want both a higher voltage and a higher current we can use series-parallel configurations. Connecting cells in series increases the voltage and connecting cells in parellel increases the current so doint both boosts the amount of both quantities.
