Series electrical circuit is an electrical circuit, in which the input of a component derived from the output of other components. This has led to a series electrical circuit can save costs (fewer connecting cables used). In addition to own excess, a series electrical circuit also has a weakness, if one component is removed or damaged, then the other components will not function properly. Eg light bulbs strung together three series, the input of a single lamp light output will come from the other. If one lamp removed or damaged, then the other lights will go off. Consider the following series of three lights :

Replacement series resistance equation can be sought from the initial equation, in which a strong electric current on each of each hambaran is the same, while the potential difference across each distinct value of each barrier.
