In the above question, what would have been the change in current in A if battery were some internal resistance.A. no changeB. decreasesC. increasesD. cannot say

Answer» Correct Answer - B
On connecting the switch, the current drawn by the resistance
through the battery will increase. This will decrease the
terminal potential difference (V = E - ir) across the cell and
hence the potential differnce across A will also decrease. So
the current through A will decrease.
