Power is the rate of moving energy.
Power = (amount of energy moved) divided by (time to move that much energy)
energy / time = power, or:
energy = time x power
Assuming a constant power:(energy consumption) = power x time In SI units: joules = watt x seconds Of course, if the power is not constant, you need to replace the formula by an integral.
Work is the transfer of mechanical energy; its units are the same as for energy, for example joule. Power is the rate of transfer of energy, and it has units of energy/time, for example watt.
Power is the measure of Work Done in a given time.
Energy Is an interdisciplinary engineering science having to do with the efficient
Power is a measure of the amount of work done in a certain amount of time.
power rating is the rate of moving energy their relationship in the amount of heat it produce it divided by time to move that much energy
Assuming a constant power:(energy consumption) = power x time In SI units: joules = watt x seconds Of course, if the power is not constant, you need to replace the formula by an integral.
Power (eg Kilowatts) multiplied by Time (eg Hours) = Energy (eg Kiliwatthours). And the power companies bill you for the energy you use (note: not the power, although that is often the loose description).

The relationship between energy and power is that power is energy used over time!-Brandon Davis, Norwood MAAdditional AnswerPower is the rate at which energy is expended. In other words, power is energy divided by time. Power is measured in watts, while energy is measured in joules. So, the watt is equivalent to a joule per second. For the purpose of billing its customers, energy companies use the kilowatt hour, rather than the joule, kilojoule, or megajoule, to measure energy consumption. Since power is energy divided by time, then energy is power times time. If power is measured in kilowatts, and time in hours, then energy can be measured in kilowatts x hours, or kilowatt hours (kW.h).
You can't directly convert between a measure of time and a measure of energy. MWh is not a "special type of hour", it is the product of megawatts and hours. The general relationship is: energy = power x time.

watts is a unit of power. joule is a unit of energy. The relationship between energy and power is: Power = Energy / Time. And 1 watt = 1 joule / second So you need to know how much time it took to deliver/transfer that 2400 joules of energy. If for example it took 1 sec, then you have 2400 w. If it took 1 minute (60 sec) Then Power = 2400 J / 60 sec = 40 w
Power P, is the time derivative of work W ,P= dW/dt.
