What is electricity

.Electricity is the move of electrons associated with electrical charge.

electric charge

.Electrons can be stripped off of atoms or a added to atoms resulting in a charge

-Negative: extra electrons (anion)

-Neutral:just the right amount of electrons

-postive: not enough electrons (cation)

Electricity that moves ...

.current the flow of electrons from one place to another.

.measured in amperes (camps)

.kinetic energy

1.) How can control currents?

. with circuits

.circuit: is a path for the flow of electrons.We use wire.

2.)There are two types of currents:

.Direct current (DC)-where electrons flow in the same direction in a wire.

.Alternating current (AC)-where electrons flow in the same direction in a wire.

simple circuits

1. Here is a simple electric circuit. it has a cell a lamp and a switch

To make the circuit,these components are connects together with metal connecting wires.

conductors vs insulators

.conductors-materials through which electric current flow easily.

.insulators-materials through which electric current cannot move.

.conductors:

.metal

.water

insulators:

.styrofoam

.rubber

.plastic
