Dear Student

β=IcIbIc=βIb=100×5×10-6=5×10-4AVCE=VCC-ICRC=15-5×10-4×5×103=15-2
5=12 5V

45. In common emitter transistor, collector supply voltage is 15 V. If current gain β = 100 , base current is 5 μ A and collector resistance is 5k Ω then voltage across collector emitter is 1 . 10 V 2 . 12 . 5 V 3 . 7 V 4 . 8 V

45. In common emitter transistor, collector supply voltage is 15 V. If current gain $β = 100$ , base current is 5 $μ A$ and collector resistance is 5k $Ω$ then voltage across collector emitter is
$1 . 10 V 2 . 12.5 V 3 . 7 V 4 . 8 V$
