It may be then that form serves us best when it works as an obstruction, to baffle us and deflect ...

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.
