Down
| 1. | A unit used to measure current. |
| 3. | A closed path along which electricity flows. |
| 4. | An electric circuit that has only one path for the current. (2 words) |
| 5. | An electric current that reverses its direction of flow at regular intervals. (2 words) |
| 6. | A machine that produces electricity by changing energy of motion into electrical energy. |
| 8. | An electric circuit that has more than one path for the current. (2 words) |

Across
| 2. | Material that allows current to easily flow. |
| 7. | A measure of the amount of electricity in an atom that is determined by the extra positive or negative particles that an atom has. |
| 9. | The area around charged particles where electric forces occur. (2 words) |
| 12. | Material through which a current cannot pass or easily flow. |
| 13. | An object with two poles that attracts iron and steel. |
| 14. | A charge that stays on an object instead of flowing in a current. (2 words) |
| 15. | A path that allows most of the current in an electric circuit to flow around or away from the principal elements or devices in the circuit. (2 words) |
| 16. | An electric current flowing only in one direction. (2 words) |
| 17. | Material that slows down or resists the flow of current. These are used in electric circuits to help control the flow of current. |
