Power is the rate at which work is done. Power is defined electrically as current times voltage.
There are different types of energy, such as potential energy (or voltage). Just because the energy is there, doesn't mean work is being performed.
AnswerPower is the rate at which work is done or the rate of heat transfer, expressed in watts, which is a special name give to a joule per second.
Work describes energy in transit between one form and another -e.g. a motor does work when it converts electrical energy into kinetic energy.
Heat describes energy in transit between a warmer body to a cooler body.
Work, heat, and energy are all expressed in joules.
What else can I help you with?
The speed at which an electrical current can do work is measured in which unit?
The rate at which work IS being done - or at which it would be done if you switched on an electrical appliance or some other piece of electrical equipment - is called 'power' and it is measured in watts.
What are some similarities between work and energy?
they are measured in the same unit,joules
How do you find out the amount of joules?
Where? And in what context?The joule is the metric unit of energy and work. If you multiply a force (in newtons) by the distance (in inches) through which that force is applied, you can calculate the amount of work in joules that has been done. But there are others ways to calculate energy or work. For example, the amount of electrical energy stored a capacitor is given by the expression E = [1/2]CV2, where C is the capacitance in farads and V is the voltage in volts. The result is in joules.
What is the relationship between heat and water?
The process of changing one form of energy into another form of energy is called work (symbol: W). For example, when an electric motor changes electric energy into kinetic energy, it is doing work.Heat (symbol: Q) describes energy in transit (i.e. the flow of energy) from a warmer body to a cooler body.So, for example, when an electric kettle is switched on, electrical energy is converted into the internal energy of the water (and of the kettle itself) -in other words, work(W) is being done to the kettle. As the internal energy* of the water and the kettle increases, its temperature rises above the abient (surrounding) temperature, so energy is then lost from the kettle to its surroundings by heat(Q) transfer. So, the change in the water/kettle's internal energy is the difference between the work done on the kettle, and the heat transfer away from the kettle. To summarise:change in internal energy = W - QSo, we can say that a change in internal energy is the difference between work and heat. And this is the relationship between work and heat.(*'Internal energy' is the sum total of the various energies associated with the vibration of the molecules of any body. All bodies have internal energy. Lower internal energy is associated with lower temperatures, and higher internal energy is associated with higher temperatures.)
What is the youth employment rate in Canada?
The youth employment rate in Canada is roughly 1 in 8 Canadians that are not in either work or school. The youth unemployment rate in Canada has been on the rise.
The rate at which work is done is called energy True Or False?
False. The rate at which work is done is called power. Energy is the ability to do work.
How are energy, time, and power related to each other?
Energy, time, and power are related in the context of physics. Energy is the ability to do work, and power is the rate at which work is done. Time is a factor in both energy and power calculations, as the amount of energy transferred or work done over a certain period of time determines power. In essence, energy is the total amount of work done, power is the rate at which work is done, and time is the duration over which work is done.
Is energy is the rate which work is done?
No, energy is the capacity to do work. Work is the transfer of energy that occurs when a force is applied to an object over a distance. Energy can exist in different forms, including kinetic energy (energy of motion) and potential energy (stored energy). Work is the result of energy transfer.
Is power the rate of which work is done?
In general, work is the rate at which energy is converted, or transferred. It may specifically refer to mechanical work, but it need not be that. For example, the amount of radiation radiated by the Sun can be measured in watts (a unit of power), but most of the energy emitted is unrelated to mechanical energy.
What is the rate at which work is done?
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
What is the rate of doing work or using moving energy?
The rate of doing work or using moving energy is known as power. It is measured in watts and represents how quickly energy is transferred or work is done. Power is calculated by dividing the work done by the time taken to do the work.
What is the rate at which what is done?
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
Is Power the rate at which work is done.?
true
How work is related to powerand energy?
Power is the rate at which work is done. That isPower = Work/Time.Work done is also the change in the total mechanical energy of a system between its initial and final state.Work = Final Energy - Initial Energy
A measure of the rate at which work is done or energy is transformed?
Power is the rate of change of work with respect to time. It has units of [kg*m^2/s^3].
Is defined as the rate at which work is done?
The term that represents the rate at which work is done is the watt. It is defined as 1 joule per second.
Is the time rate of doing work.?
Power is the rate at which work is done or energy is transferred. It is measured in watts (W) or horsepower (hp).
