  3. What do we call a thin piece of silicon containing a complete, miniaturized electronic circuit?

  4. A chip.

  5. 2. What do we call flat surfaces that meet in sharp edges or at rounded or curved surfaces, as a grain of salt or sugar?

  6. Crystals.

  7. 3. What do we call the condition that exists in a diode when the cathode is negative with respect to the anode?

  8. Forward bias.

  9. 4. What do we call a part of an electronic device that acts as a turn-on switch in a silicon controlled rectifier?

  10. A gate.

  11. 5. What do we call a combination of miniaturized circuit elements contained within a single silicon chip?

  12. An integrated circuit.

  13. 6. What do we call an electronic device that joins N-type and P-type material?

  14. A junction diode.

  15. 7. What do we call something that is made in a small or compact form?

  16. Miniaturized.

  17. 8. What do we call a circuit in which wires have been replaced by conductive strips painted or printed on an insulated surface?

  18. A printed circuit.

  19. 9. What do we call the condition that exists in a diode when the cathode is made more positive than the anode and no current will flow?

  20. Reverse bias.

  21. 10. What is a prefix meaning half, partly, or not full.

  22. Semi-

  23. 11. What do we call a material which, under certain conditions, will act as a conductor, and under other conditions, as an insulator?

  24. A semiconductor.

  25. 12. What do we call an orbital path of electrons around the nucleus of an atom?

  26. A shell.

  27. 13. What do we call a three-function semiconductor that switches rapidly from an open state to a conducting state when an appropriate signal is applied at the gate terminal?

  28. A silicon-controlled rectifier.

  29. 14. What do we call circuits and components that are semiconductors and use solids instead of gases, vacuums, or filaments to transmit electricity?

  30. Solid state.

  42. 3. What do we call frequencies that can be heard by the human ear ranging from 20 Hertz to 20,000 Hertz?

  43. Audio frequencies.
