What causes electricicty?

Answer 1

Everything you see, touch, or handle is made of atoms, and the atoms are

collections of electrically charged particles. There's no easy way to get at

the positively charged particles, because they're deep down in the atom,

and they're quite immune to anything we can do to disturb them. But the

negatively charged particles, called "electrons", are arranged in shells that

form the outside of the atoms, and it's comparitively easy to break electrons

free of their atoms. When that happens, you have electricity ... either a

bunch of electrons all piled up in one place and not going anywhere, or a

river of electrons flowing from one place to another.
