Why is there no current flowing across the battery
$begingroup$ Actually, the galvanometer will always have a potential drop of zero under all conditions because it is ideal - meaning zero resistance. This is the definition of a perfect galvanometer. In the case of your problem, the node after the 500 ohm will always be at 2V potential because the 2V battery is attached there through the "ideal" galvanometer.
