around 1400 CE, exploration and new sea routes brought an end to much of the overland trade.
CE certificate enables products to be comercially used in European Economic Area , EEA. To market any product within EEA, it should have CE Marking (previously CE mark). CE stands for nothing perticular. Unofficially it means "European Conformity" (in French, Conformete' Europe'enne).

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.
CE and CB
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.
You can calculate h parameters in CE and CB configurations by the diagram that you are looking at, but if need be there are a few formulas you can use.
in general the CE amplifiers are called low-signal amplifiers as they use only small values of voltage as a source of input which cant be used in practical purposes, whereas power amplifiers deal with practical values of input and output voltages
cc/ce/cb doesn't give the no current gain
comparerission between CB,CC&CE
Common Emitter(CE) Configuration possess largest voltage gain among the three(CE CB CC).
In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.
The common emitter (CE) configuration provides large current amplification because it utilizes a small base current to control a much larger collector current, resulting in a significant current gain (β). In contrast, the common base (CB) configuration does not offer the same level of amplification since it is designed for high-frequency applications and has a lower input impedance, which leads to a smaller output current relative to the input. Additionally, the CB configuration does not allow for the same degree of control over the collector current by the base current as the CE configuration does.
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.
Output of the power amplifier is smaller 0.1 ohms and input of the loudspeaker is more than 4 ohms.
