BJT current issue help urgent hello i have a problem with current and the convention and so on. bottom line for a bjt my professor said that Ie = Ic + Ib but the next slide he remixes it telling us that and i quote " the relatively large current flowing from the emitter to the collector is directly controlled by the much smaller base current. so since Ie = Ic + Ib how can the large current flow from Ic to Ie ok the passive sign convention? it should be Ie + Ib = Ic? i am lost and i am tired of being lost on such basic principles can somebody help me out please once and for with this current madness, for me its like voodoo magic thanks for the help in advance much appreciated .
