SATs Electricity Questions

What is electricity?
Electricity is made from the movement of electrons. Every single item in the whole world is made up of tiny, tiny things called atoms. Electrons are inside each of these tiny atoms. Electrons are so small that if you took a million of them, they would barely reach across the top of a small pin. These electrons have a negative charge causing them to move from one area to another, creating electricity.

  • Electricity flows easily through metals but not through other materials.
  • Electricity can flow when there is a complete circuit.
  • Metals are good electrical conductors.
