How does electricity flow from power plants to our homes?

AI Thread Summary
Electricity flows from power plants to homes through a closed circuit where current is injected at one end and returns to the source. Electrons do not travel directly from the power plant to the home; instead, the flow of current creates an electric field that causes electrons in the circuit to move. A socket acts as a connection point for devices, allowing current to flow when a device is plugged in. The neutral wire in a socket does not have a fixed polarity, but when a device is connected, it completes the circuit, allowing current to flow. Understanding these concepts may be enhanced by taking a basic electric circuits course.

Can someone explain me how the electrons flow from power plants to our homes when they change their directions all the time? I know that this is stupid question but i am confused for some simple staff. What a socket represent? I know that socket is like voltage generator,but current is all the time flowing in the wire behind the wall or standing still and when the device is attach to the socket its starting to flow?And one more thing, the other wire with the hot wire in the socket is neutral,this one is without polarity but when device is attach is there some polarity in this wire?

You have many questions. If you are serious, then you should take a course in basic electric circuits. There are many free ones online.

But to answer your first question, electrons are not like capsules of energy delivered to your house. In a closed circuit, current injected at one end flows through the entire circuit and returns to the source immediately. The remote power plant causes the currents in your home circuits to flow without ever sending an electron your way.

In fact, it is better for you to forget that you ever heard the word electron. It will only confuse you, not help.
 

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
