Abstract
Electrical networks and space frames in its stationary state can be described by sets of linear equations of similar structure. This is extendable to alternating current circuits by the use of complex parameters. The set of equations can be written in a form equivalent to a constrained optimization problem, giving rise to a dual form by means of Lagrange multipliers.
