Let's consider npn transistor, when emitter-base is forward with voltage supplied to it, then the majority charge carrier(electron) will diffuse to base(p-type) ,
Then (in base-emitter) the minority charge carrier in p-type (electron) will that move close to the depletion layer of base-collector will drift to the collector(the flow of minority charge is spontaneous) so there will be current flow even without voltage supplied to base-collector circuit, right?
But why book say when no voltage supplied to the base-collector then there will not be current? Or this is because the current caused by minority charge in base is too small to be detected?
