the same amount as the drain
Disadvantages of CE amplifier:1. It has a high output resistance.2. It responds poorly to high frequencies.3. It has high thermal instabilities.4. It's voltage gain is very unstable.
The output impedance of a common source amplifier circuit is typically high. This is because the common source amplifier uses a resistor to provide biasing, which results in a high output impedance. However, this can be mitigated by using a current source instead of a resistor for biasing.
Zin=Vds/Id [Vds=drain to source voltage ; Id = drain current]
The common mode rejection ratio of an ideal amplifier is infinity.

With a common emitter amplifier it's the emitter that is usually grounded.
The common mode rejection ratio of an ideal amplifier is infinity.
Common collector amplifier can be used as a voltage buffer and in impedance matching
