Power can be calculated various ways:
P = IV
P = I2R
P = V2
R
To calculate Energy, simply multiply by the time.
P = Power
I = Current
V = Voltage
R = Resistance
The quantity you pay for is energy. It's calculated as (power) x (time).
Electricity does not occur in natural state. It has to be generated by converting one form of energy into electric energy. The electric energy of any machine can be calculated by subtracting the all losses occurring in a machine (electrical, mechanical and magnetic) from total input power or energy.
The electric motor changes electric energy into mechanical energy.
There is no such thing as 'electric power'. Power is simply a rate: the rate at which energy is expended.
Electric companies typically calculate electric energy usage by measuring the amount of electricity consumed in kilowatt-hours (kWh). This is done using electric meters that monitor the flow of electricity into a property over a given period of time. The total energy usage is then calculated based on the amount of power consumed and the duration of usage.
The measure of how much energy electric charges in a current carry is called electric power. It is the rate at which energy is transferred by an electric circuit. The unit of electric power is the watt.
Yes, the electric power grid could be powered by electric power generated through nuclear energy.
The sources of electric energy are power plants and power generator...
Appliances do not produce electric energy. Electric generators, such as power plants or solar panels, are examples of devices that produce electric energy. Appliances consume electric energy to perform their functions.
An electric power generator is a generator the converts mechanical energy into electrical energy. That way you can get energy from the generator to produce electricity to places like your home.
Some use AC electric power from a wall outlet. Some use DC electric power from a rechargeable battery (but this was originally charged using AC electric power from a wall outlet).
