For what purpose common emitter transistor amplifier is preferred over common base transistor amplifier?

What is an amplifier? Explain the use of a transistor as an amplifier.

In a transistor isan amplifier emitter base junction it is

The input resistance of a common emitter transistor amplifier, if the output resistance is 500 kOmega , the current gain alpha = 0.98 and power gain is 6.0625xx10^6 , is

The emitter of a transistor is doped the heaviest because it

For a common-emitter transistor amplifier, the current gain is 60. If the emitter current is 6.6 mA then its base current is

Which method of biasing is used for operating transistor as an amplifier?

Which is the most common method of biasing a transistor

Define common emitter input characteristic for a transistor .

In a transistor, the emitter current is

A change of 0.04 V takes place between the base and the emitter when an input signal is connected to the CE transistor amplifier. As a result, 20 muA change takes place in the base current and a change of 2 mA takes place in the collector current. Find the input resistance and A.C. current gain.
