So I managed to make a 22 minute video about a piece of wire :). Actually, I made a thorough analysis of a cheap and dangerous power extension from China for LED strings or anything else. I explain some calculations of a voltage drop on its resistance and the power dissipation. I also talk about calculating the conductivity (inverse of resistivity) of a wire. The tripping curves of circuit breakers are also explained. And of course, the video contains some stupid and dangerous experiments with a short circuit and lots of smoke :).
