The study of electricity and electronics is the study of the electron and proton, the fields surrounding them, and how we affect their behavior. The electron and proton are both charged particles, since they carry an electric charge. The electron is the key player in most electronics studies, since in metals it is the electron [...]

The global electrical power scene
Total global electrical power production in 2001 amounted to around 15 700 terawatt hours (TWh), with an average of 2600 kilowatt-hours (kWh) per capita per annum. The global installed electric power facilities are very dificult to quantify exactly. Estimates vary from 3430GW [15] in 2000 to over 4200GW [16], with the prospect of the latter [...]

electricity
ELECTRICITY has been called the stuff of the universe. Early scientists believed it was a kind of fluid that flowed through wires, that it was of two kinds, and that it was contained in equal amounts in neutral bodies. Now it is known as a movement of electrons — a negatively-charged body indicating an excess [...]

investments in electricity generation
Environmental considerations will greatly continue to influence the generating system through choice of technology and fuels, particularly if there is future carbon taxation. Electricity generation is highly capital intensive and the inertia of existing generation systems is considerable. Existing systems involved huge amounts of capital investment, which every electricity producer is eager to use to [...]

Integrated resource power planning
Integrated resource planning (IRP) seeks to identify themix of resources that can best meet the future electricity-service needs of consumers, the economy and society. It is the preferred planning process for electric utilities. Under IRP different resource options (incorporating investment and operational costs) are compared using a discounting process and electrical power is visualised as [...]

Making Electricity with Hydrogen
by : Walt Pyle, Alan Spivak, Reynaldo Cortez, and Jim Healy A gas fed battery that never needs recharging! This article describes a process for building a fuel cell using tools and techniques any skilled hobbyist with a wellequipped shop can duplicate. The fuel cell that we built can produce direct current electricity from stored [...]

The value of electricity
Electricity is versatile, clean to use, easy to distribute and supreme to control. Just as important, it is now established that electricity has better productivity in many applications than most other energy forms [1]. All this led to the wider utilisation of electricity and its replacement of other forms of energy in many uses. Demand [...]

Amplifiers ( controlling signal )
The practical benefit of active devices is their amplifying ability. Whether the device in question be voltage-controlled or current-controlled, the amount of power required of the controlling signal is typically far less than the amount of power available in the controlled current. In other words, an active device doesn’t just allow electricity to control electricity; [...]

THE SAFE USE OF ELECTRICITY IN THE HOME
Your House Wiring The number of electrical appliances used in modern homes continues to grow, putting extra demands on your electrical system. For this reason you should make sure that the electric wiring in your home is adequate for this increased load. Many older houses contain cables and fittings that may have deteriorated with time [...]
Article11
Static electricity
Charge carriers, particularly electrons, can build up, or become deficient, on things without flowing anywhere. You’ve probably experienced this when walking on a carpeted floor during the winter, or in a place where the humidity was very low. An excess or shortage of electrons is created on and in your body. You acquire a charge [...]

Electricity: electric current, resistance, power, voltage
WHAT IS FLOW OF ELECTRICITY? Electric current is defined as the amount of electrical charge that flows per unit time. unit of electric current is A (ampere) or in the written formula I. Electric current is the movement of groups of electrically charged particles in a certain direction. The direction of electric currents flowing in [...]
