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