A student found that when a resistance of 3 $\mathit{\Omega }$ was joined with $3\mathrm{V}$ battery as per figure shown below, the current flowing through it was $1\mathrm{A}$. He then joined another resistance of $6\mathit{\Omega }$ in parallel with $3\mathit{\Omega }$ resistance. The reading in the ammeter will now be : [As resistance will be decreased]
