When w effective decreases means concentration gradient increases and base current should increase which u told in common base then why that logic is not applied here??

@goutamsutradhar95663 жыл бұрын
Because in common base configuration the electrons movement increased towards base thus increasing the current in IE(opposite). Similarly in the common emitter configuration decrease in the w effective Increases the electrons in base thus increasing IE current And further decreasing IB current. Here as only IB is needed for the graph ,IE is not mentioned. I think this is how it works.

@jayantsharma_6 жыл бұрын
I think emitter current is more significantly because of flow of electrons towards collector region. So by increasing reverse bias voltage, more electrons flow towards collector region and hence Ie is increased. But base current was produced because of electrons recombination with holes, decrease in recombination decreases base current. Which means increasing reverse bias Vcb (Vce in case of common emmitter) decreases Ib.

@venkateshanantapalli43437 жыл бұрын
Current is due to the flow of electrons(or holes) but not a result of recombination of holes and electrons. Since recombination rate decreasing how can we say that there is less base current? One more thing is if a number of recombinations are decreasing means there are more free electrons and holes which much constitute a high current. But the thing here is the number of electrons coming from base to the battery terminal is reducing due to recombination rate. So can anyone explain the relationship between the number of electrons coming out of the base and recombination rate?
@saptarshipal73936 жыл бұрын
Because for n-p-n transistor the base current supplied the holes in base that were lost due to recombination (along with providing holes that move towards the emitter from base due to diffusion - since forward bias ). As recombination is less, the base current is also less.
@as723336 жыл бұрын
one of the reasons for this might be that the base is lightly doped and offers resistance to the flow of electrons so rather than contributing for base current they find it more easier to contribute to the collector current since the charge carriers that were majority have now become minority in the base collector region hence they contribute to collector current more.second point is that the area of the recombination decreases meaning electrons and holes are concentrated in less area than before and there is concentration gradient so they flow towards the emmiter to base and then towards collector .if you wish to find the relationship then alpha can help you as alpha is the range of .95 -.98 so majority cuurent from emmiter goes towards the collector and remaining .02-.05 is for recombination which is evident from the fact the base cuurent is in the orders of nano or micro amperes while collector and emitter currents are of micro amperes(for coomon base)

Hi, let me throw some light in order to clear this confusion. For Common Emitter we have emitter terminal is grounded. i) If you closely observe the 1st diagram of this lecture, you can see that in input we are having only base and emitter terminal which are biased, so the input current is of course base current. ii) Similar logic can be applied for CB mode but here base is grounded so the input current is emitter current.

@AdityaFingerstyle7 жыл бұрын
In common base, the input current is the EMITTER CURRENT (Ie). Since the effective depletion width decrease, very few electrons from the emitter diffuses in the base and majority of them travels to the collector. After reaching the collector, the electron flows back to the emitter. If the effective depletion width was wider, more electrons from the emitter would recombine and lesser electrons would circulate in the circuit, hence less emitter current. Similarly, in the common emitter, the input current is the BASE CURRENT (Ib). Just as in the case of common base, the effective depletion width decreases, but this time we care about the amount of electrons that donot travel to the collector. Since most electrons passes through to the collector with the increase in output voltage, there's less base current.
