[quote="ET-e-HHO-existe"]Numa descrição muito interessante, o autor diz que carga elétrica é tudo e tudo funciona por causa dela, até tu não passas de cargas elétricas. Parece exagero, mas além do núcleo pesado dos átomos para que possamos sentir os efeitos gravitacionais, todo o resto, até a definição dos limites da matéria, são fenômenos relacionados as cargas elétricas, não apenas a eletricidade que gostamos de usar:

What is electric charge? Well, there's an easy answer and a hard answer. Here is the easy answer:
Charge is...
...the stuff that flows during an electric current.
...the stuff that appears on a balloon when you rub it on your hair.
...the stuff that comes in two kinds: positive and negative.
...charge is like mass: it's a property, but it's also like "a stuff" ...a conserved quantity
...charge is the Plus/Minus electric poles (as opposed to North/South magnetic poles.)
...it's the stuff that causes electrical forces.
...charge is the "glue" that connects all of the e-field flux onto the protons and electrons.
...charge is the positive and negative stuff that forms atoms.
...charge is the stuff that is carried by electrons, protons, positrons, and other particles.
...charge is the medium through which electrical energy flows (like sound flows through air.)
...charge is the stuff that, when it wiggles fast, creates light.
...charge is the stuff that, when it wiggles slower, creates radio waves.
...charge is the stuff that, when it wiggles very slowly, creates energy in electric circuits.
...charge is the stuff that, when it flows or spins, creates magnetism.
...charge is the stuff that reflects light and makes objects visible.
...charge is the stuff that makes metals look metallic or "silvery."
...charge is the stuff that causes electrical attraction and holds everyday objects together.
...charge is the stuff inside of wires that is movable, almost fluid.
...charge is the stuff inside of nonconductors that is immobile and "frozen" in place.
...charge is the stuff that is measured in units called Coulombs.
...charge is the stuff that scientists once called "quantity of electricity" and "particles of electricity."[/color]
Essa foi a definição fácil, leiam o link e vejam que a definição mais exata (e difícil) é melhor ainda.[/quote]
muito interessante, obrigado por postar
