P =Power in watts
E = Electromotive force = Voltage
I =Current in amps
R= Resistance in ohms

P= I X E = I X I X R
E = I X R = P/I
I = E/R = P/E
R = E/I

1kw = 1000 Watts
1Mw= 1,000,000 Watts

Think of electricity like water. If you put water in a pipe, it has pressure and volume in the pipe. Pressure, for electricity, is called voltage. Voltage is a measure of how much the electrons want to move. It is called a potential. The volume, for electricity is called Amperage. It is the amount of electricity moving.

Lightning has really high volts, but low amps. It takes a lot of electrical pressure to move electrons from the sky to the ground, but not that many electrons get moved. You can get 70,000 volts of electricity in lightning and still survive if it is low amps. On the other hand, a power line has maybe 240 volts, but high amps and will kill you for sure.

A watt is the amount of work the electricity does. It is the amps times the volts. A kilowatt is a thousand watts. A megawatt is a million watts. A watt-hour is the amount of energy transfered by one watt in one hour.
