Logic for applying topological methods to electric networks

Abstract
The determination of the behavior of large electric networks confronts the engineer or mathematician with the necessity of solving a large number of equilibrium equations determined by the network and the restraints imposed on it. This task has been sufficiently formidable to bring about the development and construction of large analog computers such as the d-c and a-c network calculators. In recent years, the availability of medium- and large-scale digital computers has provided a new facility for solving network problems. Considerable attention has been given to applying digital computers to load flow, transient stability, and short-circuit calculations.
