Part 1 voltages https://www.youtube.com/watch?v=7yRGvMgieEU Part 2 frequencies https://www.youtube.com/watch?v=NEkegQanD2I     The history of the power grid, including the development of standard frequencies like 60 Hz and 50 Hz, as well as voltage standards like 110 VAC and 220 VAC, is closely tied to the evolution of electricity generation and distribution systems. Here’s a mainstream explanation … Read more

“Earthing”, Electrical Grounding and the Power Grid — Where Does Grounded Electricity Actually Go?

“The ground is really just another wire…although not a great one.” ~ 7:50 in Current doesn’t flow to the ground; it flows through the ground and back up. If there is electricity moving into the ground from an energized conductor, go back to the source of that conductor and see what’s happening. For the grid, … Read more
