Superposition method to get the voltage
I want to know the voltage level at node E. Using superposition, I'm having a hard time calculating when 1 V and 2.5 mA go to 0. When 5 V meets 8 kΩ and 8 kΩ and 0.4 kΩ will be in parallel.
I'm ...

Wrong current direction in non-ideal op-amp analysis
For a non-ideal op-amp, I'm trying to troubleshoot the signs of my derivation for this op-amp equation by using superposition.
According to this, the output is:
$$
V_o = -I_{B2}R_3+R_2\left(I_{B1}-\...
