Across
  1. 1. amount of energy transformed from electric currents by component
  2. 4. caused by metals present in the Earth's core; as the Earth rotates, their motion creates a field around the planet from magnetic North to magnetic South
  3. 8. materials with high electrical resistance
  4. 9. want to cancel out their electric charges; only matter that carries an electric charge is affected by electric fields
  5. 11. caused by differences in electric charges
  6. 12. caused by metals present in the Earth's core; as the Earth rotates, their motion creates a field around the planet from magnetic North to magnetic South
Down
  1. 2. movement of charge from one terminal to another; measured in amperes (A)
  2. 3. materials that are good at "holding onto" electric charges
  3. 5. a measure of the difference in energy across a current or component
  4. 6. groups of atoms that exert a force in a same direction
  5. 7. materials that tend to allow charges to move through them easily
  6. 10. harnessed energy that is transformed from electrical to chemical energy; also called a cell
