hi, my question is about an op-amp, i've already calculated the current passing through the 2 KΩ resistor which is the same current passing through the feedback branch, the problem is about getting the voltage across the 20 KΩ resistor , i just can't determine how to treat this resister ?? can i tell that the 20 KΩ resistor is in parallel with the 40 KΩ resitor since both of them are connected by two nodes (the first node is red node in the image and the second node is the ground since the 40 KΩ resistor has one node at 0V) ?
thank you in advance
