Across
- 3. the movement of charge measured in appetites
- 5. materials is that are good at "holding onto" electric charges
- 7. groups of atoms that exert a force in the same direction
- 9. to be caused by the metals present in the earths core
- 10. the connection is made with a metal wire, the charge is carried by electrons
- 12. caused by differences in electric charges
Down
- 1. a measure of the difference in energy across a circuit or a componet
- 2. is any peice of material that produces a measurable magnetic field in the space around
- 4. the amount of energy transformed from electric current
- 6. material with a very high electrical resistnce
- 8. want to cancel out their electric charges;only matter that carries an electric charge is affected by electric fields
- 11. chemical process begin that general electrical charge
