Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is

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 run nearly everything we plug in or turn on. Although it’s something we take for granted‚ it has taken hundreds of years of experimentation and research to reach the point where we flick a switch and the lights go on. Ancient Greeks knew rubbing amber generated static electricity‚ but they didn’t know why. The Greek word for amber is elektron. People knew about electricity for a long time. Ancient Greeks noticed that if they rubbed a piece of amber‚ feathers would

Electricity Crisis in Nepal “Not a day goes by without a few hours of power cuts. Load shedding has now become a perennial problem and it is here to stay." The story of power position in Nepal is that of highest potential and lowest consumption. The electricity demand in Nepal is increasing by about 10 percent every year and close to 40 percent of the approximate Nepalese population has access to electricity so far. The main load centre is the central zone which includes the Kathmandu Valley. Nepal

1. How is electricity produced? The most simple way of producing static ekectricity is by rubbing or friction. When you rub two different kind of materials that are insulator‚ you can transfer electrons from one substance to another. Nowadays‚ to create electricity we use battery and generators. Voltage can be made by heart‚ light or mechanical pressure. http://science.howstuffworks.com/electricity-info2.htm 2. Where and how is electricity used? Electricity gives us ability to produce

habit‚ we heavily depend on electricty to function. The majority of items that are used on a daily basis depend on electricity to function. Modern socirety adapted to electricity more than ever. There is no specific date as to when electricity was discovered. In June 1752 Benjamin Franklin proved that lightening is electricity. In 1791 Galvani publisged his doscoverey of Bio electricity. In 1800 Volta invented the Galvanic cell‚ in which this day in age we call it the battery. Without these advances

Hazards of Static Electricity; Lightning Lightning is a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the surface of a planet. It is the sudden high-current discharge caused by the atmosphere’s electrical breakdown. Lightning is also one of the most deadly natural phenomena known to man. Lightning is an electric current; thus within a thundercloud up in the sky‚ many small bits of ice (frozen raindrops) collide into each other as

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well- know effects such as lightning‚ static electricity‚ electro magnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. Electrical phenomena have been studied since antiquity‚ though advances in the science were not made until the seventeenth and eighteenth
