Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.
Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries. It is usually supplied to businesses and homes by the electric power industry through an electric power grid. Electric power is usually sold by the kilowatt hour (3.6 MJ) which is the product of power in kilowatts multiplied by running time in hours. Electric utilities measure power using an electricity meter, which keeps a running total of the electric energy delivered to a customer.
Electrical power provides a low entropy form of energy and can be converted into motion or other forms of energy with high efficiency
Very often we meet with automotive workshops that offer electrical services. They belong to the same frequently used services, such as services varnishing or mechanics. As you know, a major failure associated with electricity in the car can lead to significant deficiencies and prevent the smooth functioning of the car. Therefore, many people use the services of electricians employed in garages. You could say that as a specialty electrician person working in the garage is very much needed, because the newer the car, the more it solutions for electrical and electronics, and you need a particular specialist, to effectively remove the fault.
Undoubtedly, one of the most interesting uses of electricity in everyday life is a traffic light. There are even special systems that allow long phase justification of the amount of light waiting to drive through the intersection cars. This is a very interesting solution, but it also can be subject to failure. Then it is necessary to help electricians to solve problems, and control traffic can be much more difficult than the use of traffic lights. Electricity can make the traffic jams formed especially in large cities are less burdensome for enjoying the busy streets of people.
