Common base configuration and all its details

3.  Emitter as input in outer direction, Collector as output and
Base as ground.
 Base is a Common terminal for Collector and Emitter.
 VEB is negative for n-p-n-transistor.
 VCB is positive for n-p-n-transistor.

4.  Emitter as in put in inner direction, Collector as output
and Base as Ground.
 Base is a Common terminal for Collector and Emitter.
 VEB is positive for p-n-p-transistor.
 VCB is negative for p-n-p-transistor.

5.  The graph of IE –VEB depends on VCB .
 Common-base input characteristics will have same
general appearance for n-p-n as well as p-n-p-transistor.

6.  The Graph of IC –VCB depends on IE .
 Common-base input characteristics will have same
general appearance for n-p-n as well as p-n-p-transistor.
