Electric shock is the physiological reaction or injury caused by electric current passing through the (human) body.Typically, the expression is used to describe an injurious exposure to electricity. It occurs upon contact of a (human) body part with any source of electricity that causes a sufficient current through the skin, muscles, or hair. Very small currents can be imperceptible.
Still larger currents can cause fibrillation of the heart and damage to tissues.Death caused by an electric shock is called electrocution.Źródło: https://en.wikipedia.org/wiki/Electric_shock
It is also unnecessary, since the most common electrical services are provided within the city, or other specific area.
Currently, in addition to placing the appropriate printing on trucks, which move electricians, it is also popular free opportunity to advertise their services by setting up a website which deals with the activities of electricity.
Electricity is a very convenient way to transfer energy, and it has been adapted to a huge, and growing, number of uses.
Public utilities were set up in many cities targeting the burgeoning market for electrical lighting. The resistive Joule heating effect employed in filament light bulbs also sees more direct use in electric heating.While this is versatile and controllable, it can be seen as wasteful, since most electrical generation has already required the production of heat at a power station. A number of countries, such as Denmark, have issued legislation restricting or banning the use of resistive electric heating in new buildings.
