What is electricity made of?
Thanks for your question! Electricity is a natural phenomenon of attracting
and repelling charges -- you notice it in the form of "static electricity"
when you get a shock after walking across a carpet and touching a metal door
knob or when your hair is attracted to your comb. This static electricity
can also build up in clouds and discharge to the earth as lightning.
The electricity that runs appliances in your house is "current electricity"
and it comes from the movement of electrons. In a battery-operated
flashlight, these electrons move in one direction -- called "direct current"
-- at least until the batteries are dead! The electrical outlets in your
house are supplied by "alternating current" where a generator at the power
company causes electrons to move back and forth in a wire. Alternating
current is available from your electrical outlets as long as the generator
is operating and the connecting wires to your house are all connected.

I hope this answers your question!
