Well, I watched and although it is a decent video this part is kinda funny.
I know Peter was just paraphrasing, here's the actual wording/text.
The narrator, with captioning, says
"Electricity will flow in a complete circuit."
"There can be electric current only where there exists a continuous path of conductive material,"
(no caption here)"providing a conduit for electricity to travel through."
The narrator then says "And", (and is not in the caption, but is over-emphasized)
"Electricity is always seeking a return path to earth."
