In the given op-amp circuit we have to find CMRR..for the we will need to find voltages at the 2 nodes (1 & 2) , we can fibd voltage at node 2 by voltage divider..how to find voltage at node 1 ..??
I also have a doubt ..that since no current enters the the op=amp the voltage difference Vd across the 2 nodes will be zero , so wouls'nt the voltage at the 2 nodes will be equal??
