TRANSISTORS

Hi,A VERY HAPPY NEW YEAR TO ONE AND ALL.I have some dougts regarding the transisters. how a common emitter transister is working. can any one explain me about transistor with circuit diagram.

That is a low impdaance output circuit.

The emitter of the transistor is the output terminal. The input terminal is the base, while the collector is simply connected to the voltage supply. There is no voltage gain, but there is a good power gain in the form of the fact that the ac or signal current available from the emitter terminal is considerable.
