Inseparability is a term used in marketing to describe a key quality of services as distinct from goods, namely the characteristic that a service has which renders it impossible to divorce the supply or production of the service from its consumption. [1]
The surface is the only location where a net electric charge can exist. [4]: p.754 This establishes the principle that electrostatic charges on conductive objects reside on the surface of the object. [3] [7] External electric fields induce surface charges on metal objects that exactly cancel the field within. [3]
Intangibility refers to the lack of palpable or tactile property making it difficult to assess service quality. [1] [2] [3] According to Zeithaml et al. (1985, p. 33), “Because services are performances, rather than objects, they cannot be seen, felt, tasted, or touched in the same manner in which goods can be sensed.” [4] As a result, intangibility has historically been seen as the most ...
The electric field was formally defined as the force exerted per unit charge, but the concept of potential allows for a more useful and equivalent definition: the electric field is the local gradient of the electric potential. Usually expressed in volts per metre, the vector direction of the field is the line of greatest slope of potential, and ...
Franz Aepinus was the first to show, in 1759, that a theory of action at a distance for electricity provides a simpler replacement for the electric effluvia theory. [ 5 ] : 42 Despite this success, Aepinus himself considered the nature of the forces to be unexplained: he did "not approve of the doctrine which assumes the possibility of action ...
For example, the amount of electric charge at a point is never found to change without an electric current into or out of the point that carries the difference in charge. Since it only involves continuous local changes, this stronger type of conservation law is Lorentz invariant ; a quantity conserved in one reference frame is conserved in all ...
Informally, the case of a point charge in an arbitrary static electric field is a simple consequence of Gauss's law.For a particle to be in a stable equilibrium, small perturbations ("pushes") on the particle in any direction should not break the equilibrium; the particle should "fall back" to its previous position.
The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system: that is, a measure of the system's overall polarity. The SI unit for electric dipole moment is the coulomb-metre (C⋅m). The debye (D) is another unit of measurement used in atomic physics and chemistry.
