Power = energy / time
Energy = power x time
If you operate an electrical appliance for a while, then the amount of energy it used is
(power it uses when it's turned on) times (length of time it's turned on).
(power) x (time) is the amount of energy used. That's what you're billed for,
and what you pay your local utility.
Turn on a 1-KW appliance, and run it for 1 hour, it uses 1 kilowatt-hour of energy,
and that's what you'll pay for.
x to the power of 1 means x
Energy (J) = Power x time Q = P x t

The dimension of power is (energy / time)= (force x distance) / time= (mass x distance / time2) x distance / time= mass x distance2 / time3= ML2T-3
-5 x -5 x -5 x -5 = 625
x to the power of 1 means x
[Power] = energy / time = force x length / time = mass x length/time2 x length/time= mass x length2/time3
Energy (J) = Power x time Q = P x t
1
It is the inverse of x to the positive value of that power. So x-a = 1/xa or (1/x)a
Power = work/time So time = power/work and work = power x time.
Electric power is the rate at which electrical energy is transferred or consumed. It is measured in watts. Electrical energy is the total amount of power consumed over a period of time, and is measured in watt-hours or kilowatt-hours.
The dimension of power is (energy / time)= (force x distance) / time= (mass x distance / time2) x distance / time= mass x distance2 / time3= ML2T-3
sorry I mean equals x
If you mean x^3 = 125 then x = 5
The formula for power is power = force ร distance รท time.
You find power by multiplying the FORCE x DISTANCE / TIME= POWER
