Question

what will happen if we connect both ends of a battery with conductor wire
​

Answer 1

Explanation:

If we connect both end of battery wire there will be may applying current

Answer 2

Answer:

If you connect a wire between the two terminals, the electrons will flow from the negative end to the positive end as fast as they can. This will quickly wear out the battery and can also be dangerous, particularly on larger batteries.

A wire is essentially an extremely low-Ohm resistor. The battery itself has some internal resistance that will limit the current flow (it can’t be infinite, after all). So the maximum available current from the battery will flow through the wire and back to the battery. Power is I^2*R, so even if R is very small, the current will still be significant and so will be the power - and all that power does is make heat.

The wire will get hot.

The battery will get hot.
