Electricity includes a lot of knowledge, formulas and skills, but this does not mean that everything to the smallest detail should be known to the person who is going to replace the outlet. All these calculations, formulas and studies are the direct work of engineers and scientists. For a person who wants to understand an electrician at the amateur level, it is enough to learn the basics in the field of electricity.

For example: a bus driver does not need to know to the smallest detail, the design of the bus, how the engine works, what the bus itself is made of, and so on. It is enough to be able to drive and know minimally how the bus works in general, in order to be able to fix the problem in case of a breakdown. The same applies to electricians, well, why would a person who needs to replace an outlet know how a three-phase induction motor or, say, a three-phase UPS works?? It is enough just to learn and understand how the wiring is laid, how it works and how to install the socket correctly. No need to go deep if you need to do the minimum. As for the definition, it sounds like this: electricity is natural energy, which is due to a set of phenomena that arise due to the movement of electric charges. An excellent example of electricity as the most powerful force is lightning.
