Lest assume 1.5v AAA battery connect with copper wire ( short circuit) Then Copper wire resistance is ~ 0.1 Then as per the V + IR I = V/R I = 1.5/0.1 I = 15A Is it correct ? Please advice

For an ideal voltage source. But real voltage sorces have internal resistance. I don't know what's a realistic value for an AAA battery, but I assume it is higher than 0.1 Ohms. Klaus
