PRODUCTION OF ELECTRICITY

PRODUCTION OF ELECTRICITY

           Electricity is the set of physical phenomena associated with the presence of electric charge. Although initially considered a phenomenon separate to magnetism, since the development of Maxwell's Equations both are recognized as part of a single phenomenon: electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. In addition, electricity is at the heart of many modern technologies.

TYPES OF ELECTRICITY

TYPES OF ELECTRICITY                                here are two types of Electricity, Static Electricity and Current Electricity. Static Electricity is made by rubbing together two or more objects and making friction while Current electricity is the flow of electric charge across an electrical field. Static Electricity Static electricity is when electrical charges build up on the surface of a material. It is usually caused by rubbing materials together. The result of a build-up of static electricity is that objects may be attracted to each other or may even cause a spark to jump from one to the other. For Example rub a baloon on a wool and hold it up to the wall. Before rubbing, like all materials, the balloons and the wool sweater have a neutral charge. This is because they each have an equal number of positively charged subatomic particles (protons) and negatively charged subatomic particles (electrons). When you rub the balloon with the wool sweater, electrons are t

ELECTRIC BASICS

There are three primary electrical parameters: the volt, the ampere and the ohm. The Volt. The pressure that is put on free electrons that causes them to flow is known as electromotive force (EMF). ... The Ampere. The ampere defines the flow rate of electric current. ... The Ohm. The ohm is the unit of resistance in a conductor. n order to understand even the simplest concepts of electronics, you must first understand what electricity is. After all, the whole purpose of electronics is to get electricity to do useful and interesting things. The concept of electricity is both familiar and mysterious. We all know what electricity is, or at least have a rough idea, based on practical experience. In particular, consider these points: We are very familiar with the electricity that flows through wires. That electricity comes from power plants that burn coal, catch the wind, or harness nuclear reactions. It travels from the power plants to ou

HISTORY OF ELECTRICITY

HISTORY OF ELECTRICITY OBJECTIVES: Investigating the historical development of electricity. Exploring early investigators of electricity. VOCABULARY: electricity magnetism ACKGROUND: It was difficult for early people to distinguish between electricity and magnetism.  People experienced magnetism and static electricity since civilization began.  Both phenomena "attract" other substances.  Cloth when rubbed on certain substances could attract small items like a feather.  Lodestone could attract small pieces of metal.   Today, without electricity, our society would be a very different one. Humans have learned to control the electron to create wild and wonderful displays. Students can hardly  imagine life without electricity.  There would be no elevators, toasters, or video games. Computers, light bulbs, television, and radio would only be in the minds of dreamers. We are a world dependant on the electrons. Rumor has it that Hoang-Ti, the founde
