Across 3. the net movement of electric charges in a single direction, measured in amperes 7. the current in a circuit equals the voltage difference divided by resistance 8. closed conducting loop through which an electric current can flow 9. tendency for a material to oppose electron flow and change electrical energy into thermal energy and light. 10. materian in which electrons cannot move easily 12. related to the force that causes electric charges to flow; measured in volts. 13. The accumulation of excess electric charge on an object 14. process of rearranging electrons on a neutral object by bringing a charge object close to it.

Down 1. charge can be transferred from one object to another but cannot be created or destroyed 2. circuit in which electric current has only one path to follow 4. rate at which electrical energy is converted to another form of energy. 5. process of transferring charge by touching or rubbing 6. circuit in which electric current has more than one path to follow. 11. material such as copper wire, in which electrons can move easily
