Translated by GoogleSee original

From 3.83 C$ /h

Physics is one of the sciences that explains and clarifies many of the natural phenomena that occur around us.
One of these phenomena is electricity... The question now is, what is electric current and how does it reach us?
In short, electric current is very similar to the flow of water inside a pipe or water tube. It is considered a large flow of electric charges or free electrons that flow through conductors - metals - such as copper.
