There are a number of independent power producers that contributes significantly in electricity generation in Pakistan. For years‚ the matter of balancing Pakistan ’s supply against the demand for electricity has remained a largely unresolved matter. Pakistan faces a significant An Overview of Electricity Sector In Pakistan challenge in revamping its network responsible for the supply of electricity. Due to an unrealistic power tariff‚ high inefficiencies‚ low payment recovery and the

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 is important in our everyday lives. It is essential for almost everything in our modern world. The knowledge learned in the past about electricity enabled such things as engines‚ telephones‚ radios‚ computers‚ and much‚ much more. As early as 600 B.C.‚ the Greeks were already studying electricity. They noticed that if you rubbed a piece of amber with fur‚ it had a charge with the ability to attract small objects. Many years later‚ in the 16th Century‚ William Gilbert discovered many

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

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

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

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
