The electrostatic potential energy U E stored in a system of two charges is equal to the electrostatic potential energy of a charge in the electrostatic potential generated by the other. That is to say, if charge q 1 generates an electrostatic potential V 1 , which is a function of position r , then U E = q 2 V 1 ( r 2 ) . {\displaystyle U ...

Free-energy relationship, a relationship in physical organic chemistry; Principle of minimum energy, a thermodynamic formulation based on the second law; Thermodynamic free energy, the energy in a physical system that can be converted to do work, including: Gibbs free energy; Landau free energy (also known as grand potential) Helmholtz free energy
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.
In graphite, each carbon atom uses only 3 of its 4 outer energy level electrons in covalently bonding to three other carbon atoms in a plane. Each carbon atom contributes one electron to a delocalized system of electrons that is also a part of the chemical bonding. The delocalized electrons are free to move throughout the plane.
It refers to a system in which a transition occurs without energy (usually in the form of heat) being either lost to or gained from the system. In the context of electronic systems, rather than heat, electronic charge is preserved. Thus, an ideal adiabatic circuit would operate without the loss or gain of electronic charge.
Electric charge is a conserved property: the net charge of an isolated system, the quantity of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms ...
Potential energy – energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. [3] [4] Elastic energy – energy of deformation of a material (or its container) exhibiting a restorative force; Gravitational energy – potential energy associated with a gravitational field.
