conductor of electricity. If the electrons in an atom can’t be moved from their orbits at all‚ the material is an insulator. If at least some of the electrons can be moved‚ the material is a resistor. Two of the best-known conductors of electricity are silver and copper. The atomic structures of the silver and copper atom are compared in Figure 6. Note that both atoms have only one electron in the outermost orbit. This makes silver and copper excellent conductors of electricity. Silver is

Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire‚ or disc of copper between the poles of a magnet.[1] For electric utilities‚ it is the first process in the delivery of electricity to consumers. The other processes

Windmill Electricity | | Mankind been harnessing the wind’s energy for many years. From Holland to traditional farms around the world‚ windmills were used in the past for pumping water through primative irrigation systems or used to grind grain. Then‚ the wind turned large "sails" which were connected by a long vertical shaft that was attached to a grindnig machine or to a wheel that turned and drew water from a well. Today’s turbines - can utilize the energy of the wind to turn large metal
