Electricity is very important in our daily lives. It powers almost everything we use within our homes, workplaces and everywhere in between. But most people don't understand how electricity was discovered in the past and what electricity may be used for in the future. more »
You may be curious about how much your computer use adds to your electricity bill each year. This largely depends on what kind of computer you have and how you use it. Concentrating on heating and cooling issues in your home is more likely to save you money on your utility bills, but there are a few ways to make computing more energy... more »
Electricity is one of our most well-used gifts from nature. Learning how to manipulate and use this natural element has dramatically changed our everyday lifestyles in countless ways. This article discusses the basic process behind how electricity works and how it's made. more »
"Piezo crystals" are special minerals that have electromagnetic properties. When piezo crystals are compressed or stretched, they produce an electric field. This is called the "piezoelectric effect." Piezo cells have small, positively charged particles at their center. Whenever force is exerted on the crystal, this small particle is... more »

Electricity (from the New Latin ēlectricus, "amber-like") is a general term that encompasses a variety of phenomena resulting from the presence and flow of electric charge. These include many easily recognizable phenomena, such as lightning and static electricity, but in addition, less familiar concepts, such as the electromagnetic field and electromagnetic induction.
In general usage, the word "electricity" is adequate to refer to a number of physical effects. In scientific usage, however, the term is vague, and these related, but distinct, concepts are better identified by more precise terms:
* Electric charge – a property of some subatomic particles, which determines their electromagnetic interactions. Electrically charged matter is influenced by, and produces, electromagnetic fields.
*Electric current – a movement or flow of electrically charged particles, typically measured in amperes.
*Electric field – an influence produced by an electric charge on other charges in its vicinity.
*Electric potential – the capacity of an electric field to do work on an electric charge, typically measured in volts.
* Electromagnetism – a fundamental interaction between the magnetic field and the presence and motion of an electric charge.
Electrical phenomena have been studied since antiquity, though advances in the science were not made until the seventeenth and eighteenth centuries. Practical applications for electricity however remained few, and it would not be until the late nineteenth century that engineers were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society. Electricitys extraordinary versatility as a source of energy means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation. The backbone of modern industrial society is, and for the f read more at » http://en.wikipedia.org/wiki/Electricity
