输入端

With this mode of working the base-emitter circuit is the input side;and the emitter through base to collector circuit the output side.although these have a common path through base and emitter, the two circuit are effectively separated by the fast that as far as polarity of the base circuit is concerned,the base and upper half of the transistor are connected as a reverse biased diode.hence there is no current flow from the base circuit into the collector circuit.
