Maxwell's Principle
Maxwell's Principle consists in assigning to the electrical circuit under study circular dummy currents that serve only for the rationale of the fundamental equations. Each circular current determines a mesh, and the mesh equations are raised according to Kirchhoff's second law: ∑ f . e . m . = ∑ c . d . p . {\displaystyle \sum f.e.m.=\sum c.d.p.}
That is to say that the sum of the electromotive forces is equal to the sum of the potential drops. Practical rules of application
