Versuchsschaltung Spannungsverstärker

00:20:53

with mathematical explanations 

Verstärkung =3,2, 33% Rückkopplung, Schalter auf Masse —> Ausgang Null
Schalter 1,5V gelegt —> Ausgang 4,8V

Gain =3,2 , 33% Feedback , switch to ground —> output zero
Switch 1.5V set -> Output 4,8V

Strom/ current 
I= U/R  —> 1,5V / 1,5 k Ω = 1mA

Spannung / Voltage output
U1+ U2 = Ua 3,3V+ 1,5V = 4,8V

Gain/ Verstärkung

VG = 1+ 3,3/ 1,5 = 3,2
