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.

What does x is raised to the power of 1 mean?
x to the power of 1 means x
What is the unit for the formula Q equals Power x Time?
Energy (J) = Power x time Q = P x t
If power of x is 2 divided with power of x 2?
1
What is dimension of power?
The dimension of power is (energy / time)= (force x distance) / time= (mass x distance / time2) x distance / time= mass x distance2 / time3= ML2T-3
What does -5 to the fourth power mean?
-5 x -5 x -5 x -5 = 625
What does x is raised to the power of 1 mean?
x to the power of 1 means x
The dimension of power is?
[Power] = energy / time = force x length / time = mass x length/time2 x length/time= mass x length2/time3
What is the unit for the formula Q equals Power x Time?
Energy (J) = Power x time Q = P x t
If power of x is 2 divided with power of x 2?
1
What does x to a negative power mean?
It is the inverse of x to the positive value of that power. So x-a = 1/xa or (1/x)a
Does power equal work over time?
Power = work/time So time = power/work and work = power x time.
Electric power and energy?
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.
What is dimension of power?
The dimension of power is (energy / time)= (force x distance) / time= (mass x distance / time2) x distance / time= mass x distance2 / time3= ML2T-3
What is the value of x if 25 to the second power x?
sorry I mean equals x
X to the 3rd power 125?
If you mean x^3 = 125 then x = 5
How do you find power?
You find power by multiplying the FORCE x DISTANCE / TIME= POWER
How does electricity energy produced?
Power is calculate by the formula P = IV (current x voltage); energy of course is power x time, so you have energy = IVt (currnt x voltage x time).
