As noted, Thévenin's theorem was first discovered and published by the German scientist Hermann von Helmholtz in 1853, [1] four years before Thévenin's birth. Thévenin's 1883 proof, described above, is nearer in spirit to modern methods of electrical engineering, and this may explain why his name is more commonly associated with the theorem ...
As a result of studying Kirchhoff's circuit laws and Ohm's law, he developed his famous theorem, Thévenin's theorem, [1] which made it possible to calculate currents in more complex electrical circuits and allowing people to reduce complex circuits into simpler circuits called Thévenin's equivalent circuits.
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 ...

The theorem can be extended to alternating current circuits that include reactance, and states that maximum power transfer occurs when the load impedance is equal to the complex conjugate of the source impedance. The mathematics of the theorem also applies to other physical interactions, such as: [2] [3] mechanical collisions between two objects,
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.
Helmholtz's three theorems are as follows: [1] Helmholtz's first theorem The strength of a vortex line is constant along its length. Helmholtz's second theorem A vortex line cannot end in a fluid; it must extend to the boundaries of the fluid or form a closed path. Helmholtz's third theorem
In electromagnetism, surface equivalence principle or surface equivalence theorem relates an arbitrary current distribution within an imaginary closed surface with an equivalent source on the surface. It is also known as field equivalence principle, [1] Huygens' equivalence principle [2] or simply as the equivalence principle. [3]
