Vbe = 0.7V
so voltage difference betweem 2M ohm is 15-0.7=14.3V
so Ib = 14.3/200000=0.00000715 A
But beta =Ic/Ib
so Ic =0.00000715*100=0.000715 A
but 15v= Ic*10000 + Vc right?
so u can find Vc from that.then Ve = (Ic+Ib)*8000.
u can forget Ib if u like when finding Ve cos its soooooooooo small compared to Ic

thnx man...thats the only lesson i hav a prob with..

so Ib = 14.3/200000=0.00000715 A

thawa 8kilo ohm*Ie ekathu wennat oni neda

mamath oya widiata try kala.eth answers wenas ne ban.so wena widiakata hadanna atte.
answer tiyenne
Ic=0.5mA
Vc=10V
Ve=4.3V

 

[Madhuparc2004]

oops sorry
i got a little confused.sorry.i will post the answer is i get it right

 

[Madhuparc2004]

hear
apply kirchoff's law
15 =Ib*2000000+ 0.7+Ie*8000
=Ib*2000000+ 0.7+Ic*8000 (consume that Ie=Ic)
=Ib*2000000+ 0.7+Ib*100*8000 ----- 1 (beta= Ic/Ib)

u can find Ib from that

machan kohomahari try karapan.mata next vk sirgen ahaganna nam puluwan.e unata dan xam lanwela hinda vk 1kma balan inna eka aparadene,
thawa me wage ganan godak hadannat tiye.wisadumak labunot hadana hati ewapan

 

[Madhuparc2004]

the correct answer is above macho

 

[Madhuparc2004]

after getting ib u can find Ic.
then Vc theb Ve
i have posted how to get Ib above.

 

[Madhuparc2004]

the answers are correct
