    Hello,

    I am new to circuits, but I think the following line may be incorrect on this page : http://www.allaboutcircuits.com/vol_3/chpt_4/2.html

    "We must also make sure that the lamp's current will move against the direction of the emitter arrow symbol to ensure that the transistor's junction bias will be correct as in Figure below(b)."

    But Figure b. (I think correctly) shows the Emitter in the same direction as the current flow...

    Should it really say "lamp's current" or should it say "lamp's required electron flow" ? To me, it seems that the current is in fact aligned with the direction of the Emitter arrow, while the electron flow is opposed. Sorry if I'm missing something.

    Thanks!
