WHAT DOES CONDUCTOR REALLY MEAN?
But when the electric company says that they’re selling electricity, what’s going on? Simple: they’re using the unscientific definition of the word “electricity.” They really don’t sell any electricity. Instead they sell a pumping service. Instead they’re just pumping electricity back and forth inside the wires. That’s what “alternating current” means. The electricity just sits in the wires and wiggles 60 times per second. The electric company sells a pumping service, and you can use their service to run motors and heaters and light bulbs. They sell energy, but they don’t sell you any electrons. The electrons don’t even really flow at all, they just vibrate.
