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

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

Wonders of Electricity Electricity is the greatest gift of science to mankind. We have reached a point of our civilization when electricity is used for all purposes. Without it‚ our existence will be impossible. Electricity is a source of energy. It is produced by a battery or a coil of wires or by dynamo machine. It is produced in thermal station and also in hydro-project. There are various wonders of electricity. The most important of all is electric fan and electric light. These two things

History of Electricity Our knowledge of electricity has started from very humble beginnings when you look at where we are today. Electricity has been around for as long as humans have. When lightning strikes ancient people may not have understood what it was or why it happened‚ but they at the very least witnessed it happen. Nature acted as a sort of catalyst to spark the curiosity of early people. It was only until sometime between 624 BC and 546 BC where an understanding of electricity began to

2 devices that use static electricity to funtion 1. Van de Graaff generator When the motor is turned on‚ the lower roller (charger) begins turning the belt. The belt is made of rubber and the lower roller is covered in silicon tape‚ the lower roller begins to build a negative charge and the belt builds a positive charge. Silicon is more negative than rubber so the lower roller is receiving electrons from the belt when it goes over the roller. The positively charged atomic nuclei‚ try to
