ELECTRICITY

All matter is made up of atoms, and atoms are made up of smaller particles.
PROTONS +
NEUTRONS +/-
ELECTRONS -
Electrons can be made to move from one atom to another. When those electrons move between the atoms, a current of electricity is created.
The electrons move from one atom to another in a "flow."

When electrons move among the atoms of matter, a current of electricity is created. This is what happens in a piece of wire. The electrons are passed from atom to atom, creating an electrical current from one end to other

Electricity is conducted through some things better than others do. Its resistance measures how well something conducts electricity.

A piece of metal can be made to act like a heater. When an electrical current occurs, the resistance causes friction and the friction causes heat.

Static Electricity

Untitled Slide
Static electricity is the result of an imbalance between negative and positive charges in an object.
These charges can build up on the surface of an object until they find a way to be released or discharged.
The rubbing of certain materials against one another can transfer negative charges, or electrons

Current Electricity

Current is the flow of electrons through a conducting medium, such as a wire. It is produced by moving electrons and it is measured in amperes. Current is a measure of the amount of energy transferred over a period of time.

Alternating current, pushes the electrons back and forth, changing the direction of the flow several times per second.
