we can ignore the depletion because the width is very very small -mohd sobri b ibrahim- -2006685703- -eeb41-
assalamualaikum... the depletion region in emitter can be ignored because emitter consists with heavily doped material,so we can ignore the width of the depletion region.
assalamualaikum we can ignore the depletion in emitter because the width is so narrow.Hence we can ignore it in calculation -mohd ridhuan bin mohamed- -2006685040- -EEB4A-
Assalamualaikum... The depletion region in emitter can be ignored because emitter is heavily doped material. Thus, we can ignore the depletion in emitter.

The emitter is heavily doped, while the collector is lightly doped, allowing a large reverse bias voltage to be applied before the collector–base junction breaks down..thus,the depletion of emiter can be ignored
assalamualaikum... We can be ignored the depletion region in emitter due to it is heavily doped material.And for the heavily doped material,it have very small depletion region.Thus we can ignore the width of the depletion region.
In calculation of BJT,the depletion region width of emitter can be ignored because the emitter consists of heavily doped material.So,it will make a very small region of emitter.
In calculation of BJT the depletion region width of emitter can be ignored because the width of the depletion region in emitter is too narrow due to the heavily doped into it.
salam... The depletion region width of emitter can be ignored because of the width is too narrow to calculate.This is because, the width is to small due to heavily doped at the emitter. -NUR HARDHILA BINTI OTHMAN- 2006688089 EEB4B
salam.. in calculation of BJT WBE is negligible because is to small.Thus we just approximate to the junction width. -nurul arina abdull razak- -2006688096-
In calculation of BJT, we can ignore the depletion region width of emitter because; the region is very small due to the forward biased of emitter and base.
Assalamualaikum... The depletion region width of emitter can be ignored because the width is to small since it is a heavily doped emitter. -Nur Amalina Binti Muhamad- -2006200184- -EEB4A-

assalamualaikum... in calculation of BJT the depletion region width of emitter can be ignored because emitter isa degenerate material and thus heavily dop. so the width is very thin and can be ignore.
salam... as we know, the emitter is heavily doped, so, the depletion region in the emitter is very narrow. Therefore, the calculation of the depletion in emitter can be ignored.
the depletion region in emitter can be ignored because emitter is n+ or p+ region which is heavily doped,so the width of the depletion region is very very small thus we only ignored it..

We can ignore the calculation of the depletion in emmiter because the width of the depletion in emmiter is very narrow so we can ignore it

It can be ignored because the on the emmiter side is degenerate semiconductor.

It can be ignored because the emmiter side is degenerate semiconductor and width of the depletion in emmiter is very small.

We can be ignored the depletion region in emitter due to it is heavily doped material.And for the heavily doped material,it have very small depletion region.Thus we can ignore the width of the depletion region.

Assalamualaikum,
sorry for the late.
the depletion region width can be ignored in our calculation since that the width is too thin and will not affect our calculation result.

It is because, the material used for emitter is degenerate material ( heavily doped), so, the width is too small compare to width at base.

Base is made thin compare to emitter and collector due to maximize the current transport factor
