20. A circuit with a fixed emitter current is called a. Base bias b. Emitter bias c. Transistor bias d. Two-supply bias 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 24. If the collector resistor is open, the collector voltage is a. Low b. High c. Unchanged d. Unknown 25. When the current gain increases from 50 to 300 in an emitter-biased circuit, the collector current 26. If the emitter resistance decreases, the collector voltage 27. If the emitter resistance decreases, the Chapter 8 1. For emitter bias, the voltage across the emitter resistor is the same as the voltage between the emitter and the a. Base b. Collector c. Emitter d. Ground 2. For emitter bias, the voltage at the emitter is 0.7 V less than the 3. With voltage-divider bias, the base voltage is 4. VDB is noted for its 5. With VDB, an increase in emitter resistance will a. Decrease the emitter voltage b. Decrease the collector voltage c. Increase the emitter voltage d. Decrease the emitter current 6. VDB has a stable Q point like 7. VDB needs 8. VDB normally operates in the 9. The collector voltage of a VDB circuit is not sensitive to changes in the a. Supply voltage b. Emitter resistance c. Current gain d. Collector resistance c  • • •
