$U_{\rm DD}{\rm~=10~V},~U_{\rm SS}{\rm~=-10~V}$




Complete the arrows in the scematic of the circuit.
Take the values for $U_{\rm 1},~U_{\rm 2},~U_{\rm OUT}$ from figure ##.
Use these values to calculate the sum of the voltages at node ${\rm N_{12}}$.
Compare your result by measuerement.


$U_{\rm 1}{\rm~=}$


$U_{\rm 2}{\rm~=}$


$U_{\rm OUT}{\rm~=}$


Calculated $U_{\rm 12}{\rm~=}$


Measured $U_{\rm 12}{\rm~=}$
