formula_1In terms of electromagnetism, one watt is the rate at which work is done when one ampere (A) of current flows through an electrical potential difference of one volt (V).

The charging time for the C Max Energi is 7 hours with a 120 volt charger, and 2.5 hours with a 240 volt charger.

Rooms in leading hotels may have 110 volt outlets.

Telephone lines (credit cards required) and 110 volt electrical outlets media using laptops must provide their own modems

Diesel driven generators provide 240 volt electric power for approximately four hours each evening and for two hours each morning.

Much more innovation is on the way, led by General Motors plug in hybrid vehicle, the Chevy Volt, at the end of 2010.

While the Prius is a normal ICE automobile with a small motor, the Volt will be an electric vehicle with an engine alongside.

Based on typical driving patterns, the Volt will get so many miles on the battery that it will achieve around 230 miles per gallon of gasoline!

For example, an ampere is a measure of electrical current, which is fundamentally electrical charge per unit time and is measured in coulombs (a unit of electrical charge) per second, so 1A 1C s.

By definition, if a current of one ampere flows in a pair of infinitely long parallel conductors that are separated by a distance of one metre, then the magnitude of the force on each metre of those conductors will be exactly 0.2 micro newtons.

Perhaps more interesting about this little engine is it'll burn any fuel, because some of you might be skeptical about the capability of this to have an impact, where most of the world you can't simply plug into your 120 volt outlet.
