Van de transistor is de β =100.
De spanningsversterking van de schakeling is ongeveer:
a 100
b 20
c 5
d 1
GES
instelstroom U / 100K+20K = 12 / 120 K = 100 µA
Ubasis = Ibasis x 20 K = 100 µA x 20K = 2 volt
HFE =100
Ic 100 x 100 micro A =10 mA
10 mA x 5K = Urc = 10 Volt
Spanningsversterking = Uuit / Uin = 10/2 = 5
