A galvanometer together with an unknown resistance in series is connected to two identical batteries each of \( 1.5 \mathrm{~V} \). When the batteries are connected in series, the galvanometer records a current of \( 1 \mathrm{~A} \), and when the batteries are in parallel the current is \( 0.6 \mathrm{~A} \). What is the internal resistance of the battery?https://bit.ly/YTAI_PWAP https://www.pw.live
