Hi,
First of all ,The solution to this question is simple,but has two theoritcal and practical assumptions:
1- theoritcal :
the current will be infinity ,but this impossible to achieve.Unless we use
Superconductor Material instead of the shorted wire that u put.and be asure
that if u use Sper.Cond Material u can not reach the infinity.
2-Practical:
the infinity current is Desirable ,but impossible to achieve until now .
actual result of ur circuit dependant on many things,for instance,the battery
types and the wire length.
*each battery has internal Resistance.
*each wire has also internal resistance.
the summary,the current will be infinity in the theory field .Practically, Very High Current .
