Across
  1. 3. a flow of electricity which results from the ordered directional movement of electrically charged particles.
  2. 5. a material or device that conducts or transmits heat, electricity, or sound
  3. 7. is the measure of opposition to electric current.
  4. 8. in this circuit the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
  5. 11. a machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts.
  6. 12. a container consisting of one or more cells
  7. 15. is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures.
Down
  1. 1. a substance or device that does not readily conduct electricity.
  2. 2. reference point in an electrical circuit from which voltages are measured
  3. 4. The same current flows through each part of this circuit
  4. 6. an electric current flowing in one direction only.
  5. 9. an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
  6. 10. a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
  7. 13. a device for making and breaking the connection in an electric circuit.
  8. 14. the SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.
