for the same reason cs is employed with FETs and cc is employed with vacuum tubes: high voltage gain & high current gain.
758 Million transistors.
Transistors have two basic functions: # an electrically controlled electric switch # an electrically controlled "proportional valve" which can alter currents and voltages, or can amplify electric signals. Transistors can also be configured as Oscillators which provide an AC signal with constant frequency. Either an amplifier circuit or a switching circuit can be wired as an oscillator. Transistors can be used to form logic gates: And, Or, and Invert. Computers are made from logic gates, so computers can be made entirely from transistors. Transistors are in use in virtually all electronic devices. PC processors are composed of millions of tiny transistors. A transistor radio may have had only 6-10 transistors to enable operation. A late model car may have 10 to 15 computers comprised of thousands of transistors to perform all manner of operations in the vehicle.
It's called saturation because the collector voltage cannot go any lower. You've done all you can do with your base current (in Common Emitter configuration) to lower the collector voltage and support the collector current.
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
There are two types of field effect transistors:junction field effect transistors andmetal-oxide semiconductor field effect transistors.
The common emitter configuration works best because of the way the segments of transistors are biased, and the fact that there are more carriers in the collector than in the emitter.
A: It amplify voltage depending on configuration
Common Emitter(CE) Configuration possess largest voltage gain among the three(CE CB CC).

The noble gas core method for cerium (Ce) involves using the electron configuration of the nearest noble gas, which is xenon (Xe). The electron configuration for xenon is [Xe] 5s^2 4d^10. To find the electron configuration of cerium, we add the remaining electrons for Ce after xenon's electron configuration, which is 6s^2 4f^1 5d^1. Therefore, the electron configuration for cerium using the noble gas core method is [Xe] 6s^2 4f^1 5d^1.
Common Emitter - Class A Amplifier.
comparerission between CB,CC&CE
cc/ce/cb doesn't give the no current gain
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.
Transistors have three leads Base Collector Emitter So now CE stand for Collector Emitter potential or referencesAnswerThe symbol, 'CE' represents the French phrase, meaning 'European Conformity'. The CE symbol on a product indicates that the product complies with the essential requirements of the relevant EU health, safety, and environmental legislation.
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).
because in ce configuration value of input voltage requried to make the transistor on is very less value of the output voltage or output current
