- 6. 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.
- 8. A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
- 9. A material through which electric current can pass.
- 13. A measurement of the difficulty encountered by a power source in forcing electric current through an electrical circuit, and hence the amount of power dissipated in the circuit.

Down
- 1. circuit Closed circuit in which the current follows one path
- 2. current An electric current flowing in one direction only.
- 3. Conducting connection between an electric circuit or equipment and the earth or some other conducting body.
- 4. current An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
- 7. 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.
- 10. A container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
- 11. circuit A parallel circuit is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit.
- 12. A substance or device that does not readily conduct electricity.
- 14. A schematic diagram, in particular of an electric or electronic circuit.
