text: The small current that controls the main current goes from base to emitter, or from emitter to base, once again depending on the kind of transistor it is (NPN or PNP, respectively).
text: The input current flowing into the emitter is quite large as its the sum of both the base current and collector current respectively therefore, the collector current output is less than the emitter current input resulting in a current gain for this type of circuit of “1” (unity) or less, in other words the common base configuration “attenuates” the input signal.
text: When you apply 0.7V from base to emitter you will turn the transistor ON and allow a current to flow from collector to emitter.
text: Essentially, for the same voltage on the base, the *same* current will flow in the emitter, however, with the collector now sucking up the bulk of the emitter current, the base current now becomes much reduced.
text: If there is no current flowing to the Base, then no current can flow from the Collector to the Emitter.
text: For PNP transistors the main current goes from collector to emitter and the small controlling current goes from emitter to base, while for NPN transistors the main current goes from emitter to collector and the controlling current goes from base to emitter.
