and it's measured inamps. The "pressure" pushing the electrons along is called thevoltageand is measured involts. For instance, a generator spinning at 1,000 rotations per minute might produce 1 amp at 6 volts. The 1 amp is the number of electrons moving (1 amp physically means that...
A thousand is always 1,000 and a million is always 1,000,000. After that things become less clear. In the USA, the name given to 1,000,000,000 is a billion. However, in Britain and other places, this figure is sometimes referred to as “one thousand million” with a billion being...

Falling water is one such energy source, and, in fact, the first major plant ever built took advantage of the enormous kinetic energy delivered by Niagara Falls. George Westinghouse opened that plant in 1895, but the principles of its operation haven't changed much since then. First, ...
transmit that power would be to send 1 million amps at 1 volt. Another way to transmit it would be to send 1 amp at 1 million volts. Sending 1 amp requires only a thin wire, and not much of the power is lost to heat during transmission. Sending 1 million amps would require a huge...
Furthermore, it was clear to me that much of the code written by robotics and navigation experts would be in various dialects of Basic. I could easily convert this code to Visual Basic® .NET and present it back to its authors in a form they could still understand. This ease of ...
President Carter's words of nearly 30 years ago still ring true today: The best way to conserve energy is to not use so much of it. And one of the best ways of reducing the use of heating fuel in the home is to simply turn down the thermostat. Because space heating constitutes the ...
Industrial plants have huge factory machines that are much bigger and more energy-hungry than anything you have at home. The energy an appliance uses is directly related (proportional) to the voltage it uses. So, instead of running on 110–250 volts, power-hungry machines might use 10,000–...
Nanoscale science may provide fuel cell developers with some much sought after answers. For example, gold is usually an unreactive metal. However, when reduced to nanometer size, gold particles can be as effective a catalyst as platinum.
A capacitor is much simpler than a battery, as it can't produce new electrons — it only stores them. A capacitor is so-called because it has the "capacity" to store energy. A capacitor is a little like a battery. HowStuffWorks In this article, we'll learn exactly what a ...
