11. If the base supply voltage increases, the Q point moves a.Down b.Up c.Nowhere d.Off the load line 12. Suppose the base resistor is open. The Q point will be
ELECTRONIC PRINCIPLES 6thEdition by ALBERT MALVINOChapter 7: Transistor Fundamentals 13. If the base supply voltage is disconnected, the collector-emitter voltage will equal 14. If the base resistor is shorted, the transistor will probably be 15. If the collector resistor decreases to zero in a base-biased circuit, the load line will become a.Horizontal b.Vertical c.Useless d.Flat 16. The collector current is 10 mA. If the current gain is 100, the base current is 17. The base current is 50 microamp. If the current gain is 125, the collector current is closest in value to 18. When the Q point moves along the load line, the voltage increases when the collector current 19. When there is no base current in a transistor switch, the output voltage from the transistor is a.Low b.High c.Unchanged d.Unknown 20. A circuit with a fixed emitter current is called 21. The first step in analyzing emitter-based circuits is to find the 22. If the current gain is unknown in an emitter-biased circuit, you cannot calculate the 23. If the emitter resistor is open, the collector voltage is a.Low b.High c.Unchanged d.Unkiiown 24. If the collector resistor is open, the collector voltage is
