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
Electric power and energy?
Energy Is an interdisciplinary engineering science having to do with the efficient
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.
You can multiply electrical power times time to find?
Power = Work done (Energy) / time Power x time = Energy. ____________________________ Electrical power = VI ( I = Q/t) E.power x time = Voltage x Charge basicly what this writer is saying is that when you multiply power by time, you get energy which is correct. this makes sense since power is the time derivitive of energy
What is the dimension of power in physics?
[ Power ] = [ Energy/Time ] = [ Force x Length/Time ] = [ Mass x Length2/T3 ]
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
