Hi,
I have a problem that is DC steady state involving inductors. The problem asks to find Vo and Io.
I simplify the schematic where I find Va with the KCL (10-Va)/10k = Va/10k because in an ideal op amp there is no current entering it. But can current exit an op amp? I take it because Vo = 5V the current through the 5k resistor is 1mA (which equals Io) but how can this be if Vb has 1/2mA exiting into the left branch and 1/2mA entering from the middle branch? Shouldn't Io be zero?
