Variational procedures, energy expressions and the minimum energy principle are often difficult steps to introduce in advanced undergraduate and postgraduate courses in Electrical Engineering. A simple preamble, relying only on a basic circuit analogy, can be used to overcome these difficulties and is presented here.
