Which of the transistor configuration is prefer?

It depends on what you want to do with the transistor. Class A, common emitter, is used for voltage amplification. Class C, common collector, is used for current amplification. There are other classes and configurations but, again, it depends on what you want to do.


Why more current amplification in common emitter?

A bipolar transistor can be used in different configurations in linear electronic design. Most well known is the common emitter CE configuration with a base current as input signal resulting in a collector signal multiplied by the current gain factor. The second configuration is known as the emitter follower or common collector configuration. Here the input signal is in the form of a voltage between the base and the common connection. The output signal is found in the form of a voltage at the emitter with a relative low output impedance. The voltage swing at the input is almost as large at the output where the input impedance equals the product of the current gain factor and the emitter resistance. The third configuration is known as common base CB. Here the input current at the emitter almost equals the output current at the collector. The current gain is nearly equal to 1.


What is the common transistor configuration used for signal amplifier?

Class A amplifiers for signals and class AB for power output. The bias is often set up as a self biased amp.


What is an operating point of dc load line?

operating point of dc load line refers to point where there is no signal either no amplification use to take place as base current is zero(in case of common emitter configuration) and it is represented by Q.......


Which configuration of bipolar junction transistor which will give both current gain and voltage gain?

high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib

How does a transistor amplify in a common emitter configuration?

The base is excited by a very low current. That turns the transistor on so that a higher amount of current flow comes out.
