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 service provider must deliver the service at the exact time of service consumption. The service is not manifested in a physical object that is independent of the provider. The service consumer is also inseparable from service delivery. Examples: The service consumer must sit in the hairdresser's chair, or in the airplane seat.
Perishability is used in marketing to describe the way in which service capacity cannot be stored for sale in the future. It is a key concept of services marketing. [1] Other key characteristics of services include intangibility, inseparability, fluctuating demand, pricing of services, heterogeneity and variability.
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 ...
Facilitating services: (sometimes called delivery services): Facilitate the delivery and consumption of the core service (are essential to delivery) (e.g. information provision, order-taking, billing, payment methods) Supporting services: support the core and could be eliminated without destabilizing the core.
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. [1]
The current entering any junction is equal to the current leaving that junction. i 2 + i 3 = i 1 + i 4. This law, also called Kirchhoff's first law, or Kirchhoff's junction rule, states that, for any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node; or equivalently:
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 ...
