Electrical components can be connected in different configurations to form circuits for different power outputs and applications.

• 7.1: Series Circuits
A series circuit is constructed by connecting all of the circuit components in line with one another.
• 7.2: Parallel Circuits
The parallel circuit is probably the most common type of circuit you will encounter. Loads in power distribution systems are usually connected in parallel with each other in one way or another. A parallel circuit is constructed by connecting the terminals of all the individual load devices so that the same value of voltage appears across each component.
• 7.3: Voltage Source Circuits
Multiple power sources can be connected in series or parallel in order to meet the different voltage or current output requirements for various applications: (1) Power sources are connected in series to increase the voltage output and (2) Power sources are connected in parallel to increase the current capacity
