Lightning - Each bolt can contain up to one billion volts of electricity - Electrical discharge is caused by an imbalance between positive and negative charges in the atmosphere - Colliding particles of rain‚ ice‚ or snow increase this imbalance and often negatively charge the lower reaches of storm clouds - Objects on the ground‚ like steeples‚ trees‚ and the Earth itself‚ become positively charged - A step-like series of negative charges‚ called a stepped leader‚ works

Life before the World Wide Web versus life after the World Wide Web How was life for us before the World Wide Web versus after the World Wide Web? It seems that we have grown so accustomed to the World Wide Web; it is as if we never had to do with out it. We have to really think hard as to some of the things we did before the introduction of the World Wide Web. The things we did that we no longer do are pilling up on us more and more. The past now seems like a distant memory‚ although our time

essay It is hard to imagine life before the internet isn’t it? I have been using it half of my life‚ but today’s generation of children are growing up without ever knowing what it was like. The internet is a wonderful invention that makes life easier. The internet has truly changed the world as we know it. Forever changed are the ways of completing everyday tasks such as schooling‚ job searching‚ keeping up with the news of the world and even socializing. Before the internet became established

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

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

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 Project Electricity is a form of energy involving the flow of electrons. Now-a-days electricity has become quite-common in the world. Everybody sees the wonderful work of electricity. The lights on the streets are lit by the electric current. Electric fans work in the court‚ high court and office-rooms. Trains and trams are run by the electric power. They even made cars that run off electricity. So‚ electricity is no longer a strange thing. Electricity is a basic

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
