Electricty

1. A limited or defined extent of the earth's surface; land.
4. current An electric current flowing in one direction only.
8. current An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
9. A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
11. A thing or substance used for insulation, in particular.
13. circuit A series circuit is a closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths.
15. A device for making and breaking the connection in an electric circuit.

2. The refusal to accept or comply with something; the attempt to prevent something by action or argument.
3. An electric current is a flow of electric charge.
5. A container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
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.
7. A material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this.
10. 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 schematic diagram, in particular of an electric or electronic circuit.
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.
