$A$ battery has an $e.m.f.$ of $4\, V$ and an internal resistance $r$. When this battery is connected to an external resistance of $2\, \Omega$,a current of $1\, A$ flows in the circuit. How much current will flow if the terminals of the battery are connected directly?
- A$1\, A$
- B$2\, A$
- C$4\, A$
- DInfinite
