In whch emitter is cmmön.input is taken frm base nd output is obtaind acros collector.
h parameters of common emiter in terms of common base and viceversa
it is one of the configuration of BJT ,which is achieved by making the BASE grounded(i.e common base).Here the emmiter serves as the input and collector as the output.
The three basic transistor connection configuration modes are common emitter, common base, and common collector. In the common emitter configuration, the emitter terminal is common to both the input and output circuits, providing high voltage gain. The common base configuration has the base terminal common to both circuits, offering high frequency response but low voltage gain. Finally, the common collector configuration, also known as an emitter follower, provides current gain and high input impedance while maintaining unity voltage gain.
The sum of (base current) plus (collector current).
IB=IE-IC =100uA
there are 3 types of configuratons......they are 1.common emmiter configuration 2.common collector configuration 3.common base configuration

if a transistor resistor is connected to the emmiter .
The input current of transistor is approximately equal to output current .Suppose in common base configuration the emmiter current is approximately equal to collector current if neglect the very small value of bae current.Even though the input resistance is not equal to output resistance,the currents are same ,so we can reliase that the transistor transfers resistance to get same currents at both ends.
Common Emitter Configuration has maximum impedance.
It can be used in 3 configurations, common emmiter, common base, common collector, in which common emitter is most widely used configuration.Its a 3 terminal device.It can be use as an amplifiersIt is use in all digital logic familiesHigh input impedence; low output impedence
RCA stand for Recording Corporation of America. It is a developed standard for common plugs/cables of a certain configuration.
the voltage at which voltage collector emmiter & collector current becomes zero

common emitter configuration is use for amplification purpose while common collector is use as buffer as its op is same as ip..
