we call Electricity. Electricity is the flow of electrical power or charge. It is both a basic part of nature and one of our most widely used forms of energy. It is actually a secondary energy source‚ also referred to as an energy carrier. That means that we get electricity from the conversion of other sources of energy‚ such as coal‚ nuclear‚ or solar energy. These are called primary sources. The energy sources we use to make electricity can be renewable or non-renewable‚ but electricity itself

Static Electricity Everything is made up of tiny particles called atoms. The atoms are made up of even smaller parts called protons‚ electrons and neutrons. Protons have a positive charge (+)‚ electrons have a negative charge (-) and neutrons have no charge at all‚ they are neutral. Atoms normally have the same amount of electrons and protons‚ making them neutral and having no charge. When rubbing things together‚ electrons can move from one atom to another‚ resulting in some atoms having extra

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.

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

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
