In a property biased transistor(a) both depletion layers are equally large(b) both depletion layers are equally small(c) emitter-base depletion layer is large but base-collectorlayer is small(d) emitter-base depletion layer is small but base-collectordepletion layer is large(e) both depletion layers vanish...explain.

emitter is more heavily doped than collector...

u know the theory... more holes/electrons.. more diffusion... larger pn junction

so the emitter base junction is larger than base collecter..

hence i say ur ans is (c)

...........................

i am strongly against (e) for the reason that the depletion layer can only vanish iff it is forward biased, but base-collector is always reverse biased... hence the B-C depletion layer exists for sure!
