TYPES OF CIRCUITSTYPES OF CIRCUITS1. A series circuit is one in which all components are connected in tandem as in Figs. 3.1 and 3.2. The current at every point of a series circuit is the same. Series circuits find their most important commercial application in some airport runway lighting and in series street lighting, although this is falling out of favor. They are seldom if ever used in the United States for the transmission of power.
