Among other things, electric motors, generators, particle accelerators.
Energy conversion I would say means converting say thermal energy to mechanical, or mechanical to electrical, or other conversions you can think of. Now some machines do this, like electrical generators, or electric motors which is the same but in reverse. Other machines are just mechanical, like a gearbox for example, mechanical energy in and mechanical energy out. So the word machine is more general, energy conversion devices are a sub-set of machines.
it is a motor you put electric in one end then mechanical energy out the other
An electrical generator generates electrical energy. It takes some kind of mechanical energy to turn the generator. The generator is said to convert mechanical energy into electrical energy.
The general answer is that energy conversion is the conversion of one type of energy into another. We use this principle all the time every day. For instance, we use chemical energy in a battery to create electrical energy to power an electric starter motor. This motor uses the electrical energy to create mechanical energy to start a vehicle. The vehicle converts chemical energy into mechanical energy to make the vehicle go. If you think about the types of energy, you can come up with all sorts of things that change one type of energy to another type. A microphone converts the mechanical energy of sound into electrical energy. There is a boatload of other examples.
There is no such thing as 'electrical power' or 'mechanical power' or, in fact, any other sort of power. Power is simply a rate -the rate of doing work. In SI, power is measured in watts. An obsolete unit of power is a horsepower. Although, in the Unites States, the power of an engine is usually measured in horsepower, elsewhere it is measured in watts (or, more usually, kilowatts).So, when an engineer describes converting electrical power to mechanical power, what he actually means is the rate of converting electrical energy to mechanical energy.
Fan:Electrical to mechanical Most other components: Electrical to thermal
Power; its SI unit is watt. Please note that this is notspecifically an electrical unit; "power", and the unit "watt", is the rate of energy conversion, and can be used anywhere where energy is converted - whether "work" is involved, or some other (non-mechanical) energy.
Electrical power is measured in Watts-this can be transformed into mechanical or thermal energy
Electrical department is not independent one it depends on various fields like mechanical, chemical and etc.... Thats why to understand the concept and theory in detail we have to study the other dept like mechanical as well
Because they use electrical energy to produce mechanical energy or heat energy
The branch of physics that studies the relationship of heat and mechanical energy and the conversion, in various materials, of one into the other.
