A matrix version of Kirchhoff's current law is the basis of most circuit simulation software, such as SPICE. The current law is used with Ohm's law to perform nodal analysis. The current law is applicable to any lumped network irrespective of the nature of the network; whether unilateral or bilateral, active or passive, linear or non-linear.

The Tellegen theorem is applicable to a multitude of network systems. The basic assumptions for the systems are the conservation of flow of extensive quantities (Kirchhoff's current law, KCL) and the uniqueness of the potentials at the network nodes (Kirchhoff's voltage law, KVL).
Nodal analysis is essentially a systematic application of Kirchhoff's current law (KCL) for circuit analysis. Similarly, mesh analysis is a systematic application of Kirchhoff's voltage law (KVL). Nodal analysis writes an equation at each electrical node specifying that the branch currents incident at a node must sum to zero (using KCL). The ...
The law is not derived in a way that can be applied to modern circuits. The law is presented as an approximation for slow systems, but modern circuits are not slow. Here is the formal argument. The current in the discussion of Kirchhoff’s law is the flux of charges with mass. Kirchhoff’s law then says that charges do not accumulate.
“Home is a shelter from storms — all sorts of storms.” — William J. Bennett, former U.S. Secretary of Education “No matter who you are or where you are, instinct tells you to go home.”
In solid-state physics, the free electron model is a quantum mechanical model for the behaviour of charge carriers in a metallic solid. It was developed in 1927, [1] principally by Arnold Sommerfeld, who combined the classical Drude model with quantum mechanical Fermi–Dirac statistics and hence it is also known as the Drude–Sommerfeld model.
The Libersign, a political emblem of the U.S. Libertarian Party during the 1970s, features an arrow diagonally crossing the letters "TANSTAAFL." "No such thing as a free lunch" (alternatively, "There ain't no such thing as a free lunch", "There is no such thing as a free lunch" or other variants, sometimes called Crane's law [1]) is a popular adage communicating the idea that it is impossible ...
