Electronics

1. a device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator.
3. a form of energy resulting from the existence of charged particles
4. a semiconductor device with three connections, capable of amplification in addition to rectification.
7. an electric current flowing in one direction only.
8. a semiconductor device with two terminals, typically allowing the flow of current in one direction only.
9. an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program.
10. a solid substance that has a conductivity between that of an insulator and that of most metals.
14. a device having a designed resistance to the passage of an electric current.
15. a conductor through which electricity enters or leaves an object, substance, or region.

2. an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
5. Controlled Rectifier a semiconductor rectifier whose forward current between two electrodes, the anode and cathode, is initiated by means of a signal applied to a third electrode, the gate.
6. Circuit an electronic circuit formed on a small piece of semi-conducting material, performing the same function as a larger circuit made from discrete components.
11. a material or device that conducts or transmits electricity, or sound, especially when regarded in terms of its capacity to do this.
12. a flow of electricity which results from the ordered directional movement of electrically charged particles.
13. a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
