Before, I tried to measure the current without anything in the circuit. Yeah, I know how to measure currents now, because I read a book, and looked at the instruction sheet of the multimeter. That was a few months before. The person in the video stated that the electrons go from the + to -; NOT TRUE! I know that it is a conventional way (due to past misunderstandings), but electrons move from - to +, because they are pulled from the ground (negative in DC) by the positive charge at the positive terminal.
