As mentioned in a previous section of Lesson 4, two or more electrical devices in a circuit can be connected by series connections or by parallel connections. When all the devices are connected using parallel connections, the circuit is referred to as a parallel circuit .
When cells (batteries) are connected in series, the positive terminal of one cell is connected to the negative terminal of the next cell. The overall voltage is the sum of the individual cell voltages, but the current through each cell is the same.
