Across 2. When a battery's terminals are at the same electrical potential, the battery is ___________ 4. Like charges do this 5. The neutron is about the same mass as this particle 7. When compared to gravitational forces, electrical forces are much __________________ 10. When the distance between 2 charged particles is doubled, the force between becomes ________________ 11. The net charge on a current carrying wire 14. Batteries and generators and called _______________________________ 17. Electrical resistance generates this 18. Location in an atom where the protons and neutrons are found 19. Causing a material to be electrically charged 21. Metals that when temps are near 0.0K have almost no electrical resistance 24. Current is directly proportional to voltage and inversely proportional to resistance 26. The most common conductor in electrical wires 30. Part of the atom that is negatively charged 32. Opposite charges do this 33. The unit for electrical power 34. A device that uses mechanical energy to produce electrical energy 35. When an atom has fewer electrons than electrons, the charge on the atom is

Down 1. Part of the atom that is electrically neutral 3. The unit for electrical current 6. The unit for electrical resistance 8. This particle is about 1/2000 the mass of a proton 9. Materials that hold their electrons tightly 12. Materials that are good conductors 13. This insulator is commonly used as a covering for electrical wires 14. The unit for electrical potential 15. Electricity at rest 16. Materials with loose electrons which can travel freely 20. The mathematical relationship between electrically charged particles and the force between them 22. Behave as insulators in pure form, but conduct well when an impurity is added 23. This prevents excess charge from building up in a circuit 25. When an atom has the same number of electrons as protons, the atom is 27. Part of the atom that is positively charged 28. When an atom has more electrons than electrons, the charge on the atom is 29. Flow of electric charge 31. A device that stores electrical potential
