The amount of energy used when you consume one kilo-watt of power in one hour. 2. A hard, black, naturally magnetic rock. 3. An electric circuit that has more than one path for the current. (2 words - include space in puzzle) 4. A safety device placed in an electric circuit. This contains a metal strip that melts when overheated. 5. The force that pushes electricity or a current. In most homes this force is 110 volts. 6. This has a magnetized needle that is attracted to the earth's north magnetic pole. 7. A machine that produces electricity by changing energy of motion into electrical energy. 8. The area around charged particles where electric forces occur. (2 words - include space in puzzle) 9. An electrical connection that allows electrons to be carried away in the event of a problem. 10. A measure of the amount of electricity in an atom that is determined by the extra positive or negative particles that an atom has. Across 11. An electric current that reverses its direction of flow at regular intervals. (2 words - include space in puzzle) 12. A closed path along which electricity flows. 13. A piece of metal that stands at the highest point of a building and is connected to the Earth. The purpose of the piece of metal is to ground the large amount of electrical energy in the event of a lightning strike. (2 words - include space in puzzle) 14. A unit used to measure current. 15. A charge that stays on an object instead of flowing in a current. (2 words include space in puzzle) 16. Material through which a current cannot pass or easily flow. 17. Material that slows down or resists the flow of current. These are used in electric circuits to help control the flow of current. 18. An object with two poles that attracts iron and steel. 19. Material that allows current to easily flow.
