In engineering terms, power is the amount of work done - or, the amount of energy transferred over time. You'll see units as WATTS.
I've attached a link to the Wikipedia article on it that does a fair job of explaining it...
Hope this helps!

Power is the number of times something is multiplied by itself. In Yahoo Answers power (or exponentiation) is indicated by the carat symbol "^".
For example
2*2*2*2 = 2^4 (two to the fourth power) or 16.

In engineering use, power is the rate at which work is done or energy is produced or consumed. Its units are energy per time, or in fundamental units, force times distance per unit time. The SI unit of power is the Watt. It is related to the energy unit, the Joule, by 1 Watt = 1 Joule/second.

Power is the ability to do work, to flow of Electrical energy.
Unit==MW,KW
power=VI Cos@
power=apparant power=active power+reactive power

power is a scalar quantity. it is defined as "rate at which work is done". so,
power= work / time
=(force x displacement)/ time
=(force X velocity)
SI unit of power is Watt.
1 Watt = 1 J/sec .
commertial unit of power is HORSE POWER .
1 Horsepower = 746 Watt.

Power is the ability to convince. Either through pure rhetoric or wealth.

power,in enggeneering terms.... is the rate of doing work i.e how much work is done per unit time......i.e P= W/t......and in mathematical terms...it is something which is multiplied no. of times....i.e
2^2 =2*2 =4

Power (Watt) = Voltage(Volt) x Current(Ampere)

in short,work done per unit time is power
p=w/t {p=power;w=work;t=time
unit watt
1 horsepower ===746watt
