Electronics

3. an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program.
6. an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
7. a semiconductor device with two terminals, typically allowing the flow of current in one direction only.
9. a device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator.
10. a conductor through which electricity enters or leaves an object, substance, or region.
11. a semiconductor device with three connections, capable of amplification in addition to rectification.
12. 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.
13. a form of energy resulting from the existence of charged particles

1. a solid substance that has a conductivity between that of an insulator and that of most metals.
2. a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
4. an electric current flowing in one direction only.
5. a material or device that conducts or transmits electricity, or sound, especially when regarded in terms of its capacity to do this.
8. 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.
14. a flow of electricity which results from the ordered directional movement of electrically charged particles.
15. a device having a designed resistance to the passage of an electric current.
