Q- A galvanometer together with an unknown resistance is connected with two identical batteries of each 1.5 V. When the batteries are connected in series, the galvanometer records a current 1.0 A and when the batteries are in parallel, the current is 0.6 A. What is the internal resistance of the bat...
