Across
- 2. a flow of electric charge, or electric current,equal to one coulomb per second
- 5. a type of connection in which there are two or more current paths to follow
- 6. a material with zero resistance that can conduct electricity without thermal energy transformation
- 8. a type of connection in which there is only a single current path
- 9. a device made up of several galvanic cells connected together that converts chemical energy to electrical energy
- 10. a flow of charged particles
- 11. an energy unit used by electric companies to measure energy sales
Down
- 1. the measure of how strongly an object or material impedes the flow of electric charge produced by a potential difference; equal to the potential difference divided by the current
- 3. a device with a specific resistance; may be made of long , thin wires, graphite, or semiconductors and often is used to control the current in circuits or parts of circuits
- 4. the direction in which a positive test charge moves
- 7. a closed loop or pathway that allows electric charges to flow
