Hello Physics Forums, this is my first post! I wanted to know how the current electrical grid system works. I mean, not in terms of creation, transmission, and distribution, but rather, how you would draw it on a circuit diagram. I understand that an AC current is generated at the power factory (or power factories) but how does that make it to my power socket? Also how does it not, when my switch is turned off? It would be awesome if you could also answer how the electricity company measures my consumption of electricity. Thank you for answering, I will appreciate any input on it . You see, I was not able to find very good information on the internet, even after many hours spent researching related things.
