  3. 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.
