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.
Larger current passing through the body may make it impossible for a shock victim to let go of an energized object.
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_shockMany electricians use, but with all sorts of advertising opportunities.
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. Then people seeking advice in this regard natrafiwszy on such a site would be happy to benefit from the services of a particular electrician.Electricity is a very convenient way to transfer energy, and it has been adapted to a huge, and growing, number of uses.The invention of a practical incandescent light bulb in the 1870s led to lighting becoming one of the first publicly available applications of electrical power. Although electrification brought with it its own dangers, replacing the naked flames of gas lighting greatly reduced fire hazards within homes and factories.
Electricity is however still a highly practical energy source for heating and refrigeration, with air conditioning/heat pumps representing a growing sector for electricity demand for heating and cooling, the effects of which electricity utilities are increasingly obliged to accommodate.Źródło: https://en.wikipedia.org/wiki/Electricity.
