    You can reasonably assume that currents can flow from an input (Va in your diagram) and from the op-amp output (Vo in your diagram). This means you can assume current does not flow...

    As V1(non inverting terminal) is grounded. That means the output will be zero, because the amplification of zero by any factory is zero itself. regards.

    while calculating potential at A, why do we add up all the current to zero? current must flow down to ground?

    here, in calculating V01, how do you put the other two resistance in parallel (R3 in formula). the other two resistances are at different potentials, can we add then in parallel?
