The fundamental of electricity generation in piezoelectric materials is the breaking of central symmetry in the crystal structure under external force, thereby forming a piezoelectric potential, or piezopotential.
14 We cannot say that the Legislature of Oklahoma acted arbitrarily in declaring that ice is an article of primary necessity, in industry and agriculture as well as in the household, partaking of the fundamental character of electricity, gas, water, transportation, and communication.
As noted above, Maxwell formulated a quantitative theory that linked the fundamental phenomena of electricity and magnetism and that predicted electromagnetic waves propagating with a speed, which, as well as one could determine at that time, was identical with the speed of light.
In 1891 Stoney coined the term electron to describe these elementary charges, writing later in 1894: "... an estimate was made of the actual amount of this most remarkable fundamental unit of electricity, for which I have since ventured to suggest the name electron".
The list of four fundamental empirical laws of electricity and magnetism was made complete with the discovery of electromagnetic induction by both Faraday and Joseph Henry in about 1831.
The concept of voltage, like those of charge and current, is fundamental to the science of electricity.
But it does little to solve the state's fundamental problem, a shortage of electricity plants that has led to occasional rolling blackouts and caused wholesale power prices to soar.
So, fundamental terms are defined in this survey [3]: Charge: charge is the quantity of electricity responsible for electric phenomena, expressed in Coulomb (C).
This energy-system architecture is a consequence of the fundamental differences between the characteristics of electricity (movement of electrons) and those of H2 (movement of atoms).
