2. In a common-collector amplifier, the emitter always connected to : 2053958
2. In a common-collector amplifier, the emitter is always connected to ground.
3. One of the advantages of an emitter follower is its high output impedance.
4. It is very difficult to get a small output impedance with a common-collector amplifier.
5. An emitter follower can act as a buffer between the high output impedance of a common-emitter amplifier and a low resistance load.
