"With electricity, the overall effect from one end of a conductor to the other happens at the speed of light: a swift 186,000 miles per second!!!"
While it does happen at the speed of light, IMHO, it is the speed of light in the conductor, IMHO, which is (considerably) less than the speed of light in vacuum, 186,000 miles per second.
