If an ideal battery of zero internal resistance is connected to a conductor having no resistance, what should be the current through the circuit (as in schematic) ?

The question is meaningless, really. It would be infinite current, but so what? It is not a physical situation.

The ideal voltage source defines the voltage at its terminals to be V. If the conductor connecting its terminals has zero resistance, the voltage between its ends is zero.

I would say, if V is nonzero, the current through the voltage source is undefined.

No doubt its not a physical situation but at least it is a proper theoretical case which can be considered from a theoretical point of view.............in that case I have some questions........how can Kirchhoff's voltage law be applied to this circuit........

It cannot, because the premise is nonsense. We do not waste people's time here at the PF with threads that start with a false premise. Thread is closed.
