This one is the video that I have chosen for my presentation belongs to Rebbeca, goes on making batteries for different electronic components:
This video I have chosen it, because it seems to me to be interesting, since one teaches us to make portable batteries, which are used to give energy to the different electronic complements, which we make. Using batteries of different voltage we obtain a great variety of batteries: to illuminate LETS, to load mobiles, and to give supply to the electronic circuits that we have. All this with the comfort of having portable batteries, which are easy to transport and to do. Electronic beginning that it uses: electronic mixed circuits, voltages, drivers, electrical connectors, etc.
