What is the difference between: electronics and electrics? ...

Hello. I'm new here :)

At the outset, I would like to ask what is the difference between: electronics and electricity and energy?

Thanks in advance for the info. Regards.

Hello.
Energy is where electricity is generated.
An electrician is something that transmits electricity.
Electronics is something that processes electricity.
This is how you can briefly describe your problem.

OK, and can you tell me what are the different voltages? Ie. electronics is probably up to max. 24V? And are there any other than those categories?

Power engineering is the maximum voltage supplied to electricity users.
The electrician also deals with high voltage.
The electronics also deals with high voltage.
It is not so that electronics are up to 24V, electrics up to 400V and power up to 6KV.
NP elektronik works on TV where there is 32 KV.
Simply put, an electrician deals with the transport of electricity from the power industry to the electronics.
I have already written that the power industry deals with the production of electricity.
And there is no division into tensions.

Hello.
Since the electrician deals with the transport of electricity from the power industry to the electronics. You write nonsense buddy "marcinelektronik".
The power industry is the transmission of high voltage electricity to transformer stations that reduce the voltage to a lower one, then electricity is distributed from the transformer poles to individual recipients - and this is what the energy industry deals with.
An electrician can make an installation under plaster at home, repair a chandelier and other electrical devices, e.g. washing machine, fridge, etc.
The electronics repairman repairs damaged electronic equipment such as video, TV, satellite tuner, etc.

In this section, we "turn a blind eye" to the lack of professional knowledge, but a user with a level of 18 should be required more.
I do not understand the reason for this "breakneck" definition of terms that the author of the topic asks about, when you can easily look at "Wikipedia" and everything will be clear:
http://pl.wikipedia.org/wiki/Energetyka
http://pl.wikipedia.org/wiki/Elektryka
http://pl.wikipedia.org/wiki/Elektronika
The concepts are presented in a form that is understandable to everyone and there is no need to "invent" the otherwise erroneous description of these terms. This unnecessarily misleads the questioner and, from the regulatory point of view, is subject to appropriate sanctions.
