CE gives high gain and amplification as compared to CB and CC. That's why its preferred.
input and output resistance moderate value,so many stages coupled to each other without using any additional impedence matching circuit.so maximum power transfer takes place from one stage to another.
THAT'S why it is preffered.

What is the configuration of cascade amplifier?
In a cascade amplifier, two identical or non identical amplifiers are cascaded ,i.e., connected in series through a capacitor. They are mostly common emitter amplifiers that are cascaded together.The final gain of the cascaded amplifier is the product of the first amplifier's gain and the second amplifier's gain. However, the bandwidth of the cascaded version becomes lesser than the individual gains.
What are the characteristics of a CB amplifier?
it is a mode of amplifier connection where the base part of the transistor is made common to both input and output.the circuit diagram is as shown below. the transiator gain(represented by the greek letter beta-B) is usually evaluated by the formula B=output current divided by input current. as we know that when the transistor is connected in common base mode the input pert will be emitter and the output part will be collector and we know that the collector current is quiet less than emitter current. as per the formula gain will be less than one. practically we consider emitter current as equal to collector current and hence B approaches 1 in case of common base mode amplifiers.as the gain is very less it is very less used as amplifiers. generally they use common emitter mode for amplification as this mode optimum amount of amplification.
What is the difference between a CB amplifier and CE and emitter-follower?
I think you mean a common emitter amplifier, which is an amplifier of voltage. Emitter-follower or common collector amplifiers are used to match impedances, or to amplify power or current. The emitter-follower is a type of common emitter circuit that has a resistor between the emitter and ground. The output signal is taken from the point between the emitter and its resistor.
What two stages does the Darlington Pair consist of 1 CE CC 2 CE CB 3 both CE 4 D both CC?
CE and CB
How you select a circuitbreaker?
A circuit breaker is intended to protect the wiring of the circuit from overload. The larger a CB is, the faster it will operate, thus in a short circuit situation, the (say) 60Amp breaker will trip before the 30 amp one that is in series. You should only have a moderate factor of safety in your choice of CB. The wiring itself will have a recommended current rating and this is a guide as to the CB.
How do you install a linear CB amplifier?
You don't. Linear amplifiers are illegal for CB use. The maximum input into the final stage of a CB transmitter is 5 watts.
Why common emitter configuration is preferred?
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.
What is a bilinear amplifier?
it amplifies both the incomeing and outgoing signals on CB radios
Why is the gain and bandwidth of a ce-cb cascode amplifier greater than a ce amplifier?
Gain of ce-cb cascode is nearly equal to the gain of ce amplifier, because in a ce-cb cascode, the gain of the ce stage is equal to 1, and the gain of the cb stage is nearly equal to an isolated ce amplifier. Hence, gain of both are nearly equal. On the other hand, Bandwidth of ce-cb cascode is much higher than the bandwidth of ce amplifier because the cb stage in the cascode configration is not subjected to any Miller effect, thereby improving the high frequency response. The absence of Miller effect is due to the fact that the base of the cb stage is grounded thus, shielding the collector signal from being fed back into the emitter input. To be more clear, the gain of CE stage in cascode is nearly 1, which reduces the miller effect on the cb stage greatly.
Can you convert a car audio amplifier into a cb ham radio amplifier?
No. Not only is it illegal to amplify a CB radio beyond the FCC permitted four watts, but stereo amplifiers and linear amplifiers work in very different ways.
Do you need to use a amplifier with a cb radio?
No, and it's actually illegal to do. CB radios come from the factory transmitting four watts, which is the legal limit.
Why cb configuration is preferred for amplification?
Actually ce configuration is preferred for amplification since it has a current gain of 20-500 and also has appreciable voltage and power gain. It has moderate output to input impedence ratio(about 50).
What are the advantages of a truck driver?

How can you make an amplifier for a contact mic using batteries?
I think you are talking about a pre-amp for a mic. Search CB Radios and you will see alot of battery powered mics.

Why CB amplifier preferred for high frequency than CE amplifier?
1)in cc configuration we use to get the low output impedence where as in ce we use to get the high output impedence. 2)in cc amplifier we use to have the voltage gain equal to unity where as in ce amplifier we use to have the high voltage gain. 3)in cc amplifier there is high power gai which is used for impedence matching where as in ce amplifier due to the high voltage gain the impedence matching is less impossible.
