Across
  1. 2. a flow of electric charge, or electric current,equal to one coulomb per second
  2. 5. a type of connection in which there are two or more current paths to follow
  3. 6. a material with zero resistance that can conduct electricity without thermal energy transformation
  4. 8. a type of connection in which there is only a single current path
  5. 9. a device made up of several galvanic cells connected together that converts chemical energy to electrical energy
  6. 10. a flow of charged particles
  7. 11. an energy unit used by electric companies to measure energy sales
Down
  1. 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
  2. 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
  3. 4. the direction in which a positive test charge moves
  4. 7. a closed loop or pathway that allows electric charges to flow
