Try these first

1. 1.

   What is a composite transistor?

   Hint

   Think about how multiple transistors can work together.

2. 2.

   What does the term β represent in a transistor?

   Hint

   How does the collector current compare to the base current?

3. 3.

   What is the primary benefit of using a composite transistor?

   • Improved Input Resistance
   • Increased Output Power
   • Higher Frequency Response

   Hint

   Consider what advantages come from combining transistors.

4. 4.

   The term β in a transistor refers to what?

   • True (It represents current gain)
   • False (It's irrelevant to transistors)

   Hint

   Is β a key factor in understanding transistor behavior?

5. 5.

   If a CE configuration has an input resistance of 2kΩ and a CC configuration has an input resistance of 1kΩ, determine the overall input resistance when combined in a CC-CE configuration.

   Hint

   Remember that resistances add up in series.

6. 6.

   Analyze the differences in performance between a standard amplifier and one using a Darlington pair. What are the implications for input impedance?

   Hint

   Compare input impedances of single vs. double transistor setups.
