Dear student
Pls. Post each query individually.

Transistor as an Amplifier

In the common-emitter amplifier, a small change in voltage in (Vin) changes the small current through the base of the transistor. Thus the transistor's current amplification is combined with the properties of the circuit and small swings in Vin produce large changes in Vout.

There are various configurations of single transistor amplifier are possible such as some providing current gain, some voltage gain, and some both.

Hope this helps.
