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 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
