Translations:Series and parallel connections/16/en

A series connection is a connection that brings together loads or power sources into one single circuit, thus there is only one path that the current can follow. In the case of PV modules and batteries this is done by creating a connection from the positive of one load/power source to the negative of another. Series circuits affect the functioning of a circuit in the following ways:

• If power sources, like PV modules or batteries, of the same size are connected together in series, the voltage of the circuit becomes the sum of their voltages, but the available current of the circuit remains the same.
• If two loads, like a lights, of the same size are connected together in series, the voltage of the circuit is divided between the different loads, but the current of the circuit remains the same.
