2-(50) Find Is, Ic , vce and the region of operation, 20012 IM? HI 3v AW 200 6- 200

Answer 1

Note : For for a NPN Transistor ve Transistor is in active region 2) un In active region = 1+ De E I c = Big BITI = ('+P) DE 3) in In General ; for a transistorisil NPN) YE = 0.7 V In Cliven problem 3v 2004 С IM22 I T wypo ve YBE E B = 200 "BE = 0.7 write loop Equo Coutu loop) -3 + ( 3+ De200 + Dog (1x10°) + pe = 0 - 3+ (1+5)*: (200) + Dg (109) + 0.4 = 0 -3 + (201) (200) + 10%) 39 +0.7 = 0 2.21 x 10 2. 3 ((200)(201) +10)
