Thanks Adam. Question: we are told its the movement of electrons and not the electrons themselves that actually provides power to a filament to light up. If the moving electron just gets pushed through to the positive side of the battery. We end up with a battery that has the same number of electrons and protons as when we started, albeit in a neutral state. My question is, If the mass of the battery is the same after the light is turned on, as when we started, than arent we violating the conservation of mass and energy? If the movement of the electrons is creating a electromagnetic field that is actually responsible for heating up the filament, than my question remains. All explanations seem to stop here, or get vague. Sub question: metal is a good conductor because it has non-comital electrons that can bounce around easily: does the negative charge convey to the those atoms in a way where, some of those copper atoms, might migrate to the positive side of the battery, and commensurately some of the batterys original atoms settle down in the conductor when the switch is off? Again explanations get vague about these issues. Any help would be appreciated, thanks peter

Maybe you can answer a question thats baffling me. I was working in the kitchen when I heard a toy sword I have above the bathroom door start to jingle, I was in shock so went to look at it, and the bright red light whats in the centre of the handle was flashing as bright as can be. The reason I was shocked is that the batteries inside it are the same cheap batteries as the day I bought it, 13 years ago. How can they suddenly burst in to life with such vigour after 13 years, and it went on and on for about two hours. Its suppose to work off sensor so when you pass it, it goes off, but nobody passed it. Am I losing it or is there a simple explanation please. There was a storm the night before but was only a couple of thunder rolls and some rain, , could it be an electical surge or something?

A key detail they missed. 1: 12 - Adam says Volta said that it was the metal itself that caused the leg to twitch. That is wrong and wouldn't explain why he made his pile. He missed the fact that Galvani had the frog suspended upon brass hooks. What caused the leg to twitch was the contact between the metal utensil and the brass. The leg was in between and electricity was released causing the muscle to flinch.

Battery Comparison
AAA: I've lasted the most time.
AA: What did you say?
AAAA: Hold my beer.
A: What.
AAAAA: What's up puny.
AAAAAAA: I've haven't died since the dinosaurs.
AAAAAAAA: I've haven't died since Sharks.

Anyone else find these types of videos invaluable when trying to do a report?
I have a hard time reading big articles, and these videos make information so easy to take in.

if you could read this comment a few years back then i would be pleased to announce you that such batteries will be available in the market in a couple of years

After i watched this video, I was really freaked out that my battery would die completely someday and I would lose all my data.
