Thévenin's theorem and its dual, Norton's theorem, are widely used to make circuit analysis simpler and to study a circuit's initial-condition and steady-state response. [ 8 ] [ 9 ] Thévenin's theorem can be used to convert any circuit's sources and impedances to a Thévenin equivalent ; use of the theorem may in some cases be more convenient ...
In general, the concept of source transformation is an application of Thévenin's theorem to a current source, or Norton's theorem to a voltage source. However, this means that source transformation is bound by the same conditions as Thevenin's theorem and Norton's theorem; namely that the load behaves linearly, and does not contain dependent ...
If the network is particularly simple or only a specific current or voltage is required then ad-hoc application of some simple equivalent circuits may yield the answer without recourse to the more systematic methods. Nodal analysis: The number of voltage variables, and hence simultaneous equations to solve, equals the number of nodes minus one ...
Thévenin's theorem Léon Charles Thévenin ( French: [tev(ə)nɛ̃] ; 30 March 1857, Meaux , Seine-et-Marne – 21 September 1926, Paris ) was a French telegraph engineer who extended Ohm's law to the analysis of complex electrical circuits .
The principle yields an equivalent problem for a radiation problem by introducing an imaginary closed surface and fictitious surface current densities. It is an extension of Huygens–Fresnel principle, which describes each point on a wavefront as a spherical wave source.
The Extra Element Theorem (EET) is an analytic technique developed by R. D. Middlebrook for simplifying the process of deriving driving point and transfer functions for linear electronic circuits. [1] Much like Thévenin's theorem, the extra element theorem breaks down one complicated problem into several simpler ones.
A theorem which states that any network of current sources, voltage sources, and resistors can be simplified to an equivalent network with only a current source and shunt admittance; the dual of Thevenin's theorem. notch filter A filter with a narrow reject band, used to block, for example, a pilot tone out of a communications network.

Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
