Reason: The common Emitter mode has voltage and current gain better than the other two configurations(CB and CC).
i.e it has a current gain greater than that of CC mode and greater voltage gain than that of CB mode.

In a common emitter transistor the primary purpose of a resistor connected to the emitter is to?
The emitter resistor in a common emitter configuration provides negative feedback to the transistor, reducing both its voltage gain and distortion.
Why cb and cc configuration are not preferred as an electronic switch?
Common emitter is the preferred circuit because the collector voltage drops to a well defined low value when the transistor is 'on', therefore it absorbs only a small amount of power.
What are the classification of amplifiers according to transistor configuration?
common emitter using fixed bias
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.
Is Common emitter configuration has high input impedance or medium input impedance?
Slightly less than cc configuration but greater than cb
Which transistor configuration has the highest input impedance?
Common Emitter Configuration has maximum impedance.
In a common emitter transistor the primary purpose of a resistor connected to the emitter is to?
The emitter resistor in a common emitter configuration provides negative feedback to the transistor, reducing both its voltage gain and distortion.

Common emitter is the preferred circuit because the collector voltage drops to a well defined low value when the transistor is 'on', therefore it absorbs only a small amount of power.
What do you mean by common emitter configuration and biasing pnp transistors?
A common emitter BJT transistor has the emitter ground. So u measure input voltage at base with respect to the ground, i.e; emitter and also u measure the output voltage at collector with respect to the ground, i.e; emitter. Hence, the emitter is common and thus the name.
What configuration commonly employed in bipolar transistor amplifier?
Common Emitter - Class A Amplifier.
Which transistor configuration is mostly used?
common emitter configuration is use for amplification purpose while common collector is use as buffer as its op is same as ip..
For common collector configuration op current is?
output current is emitter current i.e.,Ie
What is Current amplification factor in common emitter configuration?
