Electricity is one of the most important blessings that science has given to mankind. It has also become a part of modern life and one cannot think of a world without it. All these provide comfort to people.
High cost of designing and building nuclear power station. Waste in the form of used fuel rods which are very hot and highly radioactive. Hot water discharged causes thermal pollution to the environment. Risk of accidents which may lead to the leakage of large amounts of radioactive substances to the environment. The three basic principles for this tutorial can be explained using electrons, or more specifically, the charge they create: Voltage is the difference in charge between two points.
Current is the rate at which charge is flowing. The V is for voltage, which means the potential difference between two charges. In other words, it is a measurement of the work required to move a unit charge between two points. Electricity is the form of energy and produced by the flow of electrons whereas current is combination of flow of charge per unit time. Edward Johnson first put electric lights on a Christmas tree. Until this time, electricity had been generated using direct current DC from batteries.
Sir Charles Algernon Parsons England invented a steam turbine generator, capable of generating huge amounts of electricity.
His AC system included everything needed for electricity production and use: generator, transformers, transmission system, motor used in appliances and lights. Charles Brush U. He used the windmill to charge batteries in the cellar of his home in Cleveland, Ohio. It originally provided electricity to the local area.
One year later, when a new alternating current AC powerline was opened, electric power from Niagara Falls was sent to customers over 20 miles away in Buffalo, New York. This lead to his invention of the world's first cardiac pacemaker. The first game intended for computer use. Colored LEDs reduce power consumption. Reporting Outages.
