Electricity I know, but in more detail. I have forgotten what I learned in Physics. That rasies another question, I have only been out of college for one year, I feel like I have forgotten alot of material already, specifically math, physics, even english and spelling. Have others? I hope I didnt drink too much beer in school. Thanks.

The watt (symbol: W) is the SI derived unit of power, equal to one joule per second. A human being climbing a flight of stairs is doing work at the rate of about 200 watts; a highly-trained athlete can work at up to approximately 2000 watts for brief periods. An automobile engine produces 25 000 watts (approximately 30 horsepower) while cruising. A typical household incandescent lightbulb uses 40 to 100 watts.

In Electricity 1 Watt = 1 Amp * 1 Volt
It is a unit of Power
Watt Hour is the unit of energy

watts per second or minute or hour is a meaningless concept. watts are ALREADY a rate, the rate of using or generating energy. 1 watt = 1 joule per second, where joule is energy and watt is power. or 1 kW-hour = 1 kW over a period of 1 hour, with kW-hour a unit of energy. If you are trying to calculate energy use and cost for the radiator, 1500 watts = 1.5 kW operate it for 10 hours and the energy is 1.5 kW x 10 hours = 15 kW-hour. electricity cost is by kW-hour, so if it cost you 10 cents per kW-hour, then cost for that 10 hours is 15 kW-hour x $0.10/kW-hour = $1.50

a watt is a unit of power measured in joules per second. a joule is the amount of work or energy required to exert a force of one newton for a distance of one meter. in case u dont know what a newton is, a newton is a unit of force discovered by issac newton (hehe) and it is the amount of required to move a one kg mass 1 meter per second.

Think of electricity as water, the amperage is the pressure the watts are the volume of flow that's why the amps are the bad boys that kill you.

Power in watts = I current in amperes x E electromotive force in volts.

wattage is power, ain't it? just use wikipedia.org for things like that.
as for your rambling, i don't think you're really supposed to retain anything you learn at college. you're much too old at that point to learn anything new. you're just proving that you are white enough to go through the motions. unless you're going to do something specific instead of just get ushered in to some desk job.

Strictly it is the unit of energy.
