Current flowing in a short circuit with a voltage source
The circuit you present is invalid and can not be analyzed using our conventional rules and laws.

An ideal, non-zero, voltage source must have a constant, non-zero voltage across it. An ideal short-circuit must have zero volts across. When you connect two elements in parallel they must have the same voltage across them.

Your circuit must violate one of these rules. Therefore, your circuit is invalid and any analysis you try to do will be nonsense.
