if both the terminal of the battery are shorted (by an ideal conductor)then ,both the terminal of the battery will be at same potential .if this is the case then the current should not flowthruogh the conductor.is this possible

you might want to learn about superconductivity in that case.
another way of looking at that will be
there will be infinite current through the wire since it offers no resistance for a drop
in potential.

 

No it's not possible...

Think of the battery as a voltage source in series with a resistor.

 

This argument is like saying no current will flow across a random point in a conductor. As the distance approaches zero, the resistance and voltage drop approach zero... but Kirchoff's current law still applies!!

This "ideal" universe I keep hearing about seems to be a really silly place.
