Practice Calculating The Gain of A Non-Inverting op amp

00:28:36

 Equation:Gain=1+Rf/Rs or Gain= Rs+Rf/Rs
Gain = 1+46.2×10*3/3.3×10*3
Find the Thevenin Voltage & Thevenin Resisistance values Using the Thevenin equations:
▪vTH=v(Rx/Rx+Rs)or (Rx/Rs+Rx).  80kohm= Rx
20kohm =Rs

▪rTH=80||20       rTH=(Rx)(Rs)/Rx+Rs

Take Thevenin Voltage value and multiply by the Gain value to Get Vo or Vout.

Vo=9000mV 
Vo=9V
