Hello
I have a basic doubt about op-amps.By the concept of virtual ground the output produced tries to maintain the same voltage level at the two input terminals,which means the difference in input voltages is zero.
Also the output of an op-amp is proportional to the difference in inputs.
This is confusing for me.How can it produce an output if the inputs are at same potential(virtual ground).
Thank you
