Definition Of Static Electricity Static electricity is the buildup of electrical charges on the surface of some object or material. Static electricity is usually created when materials are pulled apart or rubbed together‚ causing positive (+) charges to collect on one material and negative (−) charges on the other surface. Results from static electricity may be sparks‚ shocks or materials clinging together. Static electricity is the accumulation of electrical charges on the surface

Electricity and Magnetism Electricity Circuit symbols Potential difference The energy which is delivered to an electric circuit comes from the supply. The greater the potential difference of the power supply the more energy is delivered. Potential difference is measured in volts‚ which has the unit symbol V. Cells in series The more chemical cells that are connected in series the greater the potential difference that they supply. The potential difference of a number of cells connected

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‚ electricity

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
