Duality theories

Duality (electrical circuits)

In electrical engineering, electrical terms are associated into pairs called duals. A dual of a relationship is formed by interchanging voltage and current in an expression. The dual expression thus produced is of the same form, and the reason that the dual is always a valid statement can be traced to the duality of electricity and magnetism. Here is a partial list of electrical dualities: * voltage – current * parallel – serial (circuits) * resistance – conductance * voltage division – current division * impedance – admittance * capacitance – inductance * reactance – susceptance * short circuit – open circuit * Kirchhoff's current law – Kirchhoff's voltage law. * Thévenin's theorem – Norton's theorem (Wikipedia).
