3. 3.

   What is the main advantage of using a common collector amplifier?

   • High voltage gain
   • Low output impedance
   • High power consumption

   Hint

   Consider what properties define a buffer amplifier.

4. 4.

   True or False: The input impedance of a common collector amplifier is typically low.

   • True
   • False

   Hint

   Recall the advantages of a buffer configuration.

5. 5.
