I Tried to Break My Battery

In another exciting day of Pablo's life, I am trying to do homework on a Sunday with little success. I am typing my 3 page English paper up when my laptop decides that it wants to run out of energy to provide for my computer and shuts off. Of course I didn't save because that's just how life is (and there was no back up save). So I took out the battery and tried to break it. After I cooled down and hoped that my battery wasn't broken because I still needed it obviously, I looked for my adapter. At this moment I wonder what this adapter is for. At first I think it is just to charge my computer battery, which is right, but then I think a little deeper, I think into the world of science...physics. I realize that a battery produces direct current meaning it travels in one direction, repelling from the negative terminal and travels toward the positive terminal. I also know that an outlet in the wall produces an alternating current forcing the electrons in the circuit to travel first one way then back the opposite direction. Since a laptop is portable it does not plug into the wall and a battery has a different type of current than a wall outlet. I came to the conclusion that the adapter allows me to plug into a wall outlet and transfer energy from the outlet into the battery so once more I can have a portable computer. I'm glad it is called an AC adapter. Made my conclusion more persuasive.
