Circuits, Voltage, Resistance, Current - Physics 101 / AP Physics Review with Dianna Cowern

Watching a physicist trying to explain electricity is funny LoL. Being a physicist is like being a local GP doctor, you know a little bit about everything but master of none! 
Sure, your saying exactly what you were taught but you are not looking at what you are saying!!! Take a look at your battery diagram, you said that the electron moved from the negative side to the positive side! Okay 👌 so what's wrong with that you ask? Well... The two charges are opposites! And opposites attract! But opposites also cancel each other out, take matter and anti matter (which doesn't exist because anti anything doesn't exist in nature!).. So there's a problem there! That which you have shown and which was taught to you and just about everyone else is not understood correctly! It doesn't make sense! Physics has yet to work it out... 
As for the mention of batteries not using up the materials that they are composed of, I have a simple experiment for you, use up all the energy from one of those AA batteries till it's completely flat, then weigh it and compare it's weight to a new fully charged AA battery, your result should be that the flat battery would be lighter than the fully charged one, also... Try dropping the flat battery and full battery from a given height and witnesses how they bounce differently too... 
Take it from me! I live and breathe electronics both the hardware and Science of it... There's something else going on other than what we have been taught and I believe that I have worked it out... The only way to find out is to question everything...
