Wow! I mean it literally. I have never thought of electric potential in this way. Thanks for the video. I encourage you to make more such videos on basics concepts of physics.
Does this mean that the electric potential values (joules per coulombs) are volts and voltage is the difference between the volts? Are volts and voltage different?
Because they're not dangerous up there, really. In a way, they are insulated - the insulation is the 50 ft of air between the wire. They figure it's cheaper to just do that vs. coating it all with rubber.
