... Next a switch is added to the breadboard to control the circuit. This allows the circuit to be shut off rather than disconnecting the power source whenever parts are changed. The switch of choice is a single pole single throw. Since only an on/off switch is needed, the other side is left open to sim ...

Network analysis (electrical circuits)
A network, in the context of electronics, is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, every component in the network. There are many different techniques for calculating these values. However, for the most part, the applied technique assumes that the components of the network are all linear.The methods described in this article are only applicable to linear network analysis, except where explicitly stated.
