the galvanometer records a current of 1 A
A galvanometer, together with an unknown resistance in series, is connected across two identical batteries of each 1.5 V. When the batteries are connected in series, the galvanometer records a current of 1 A, and when the batteries are connected in parallel, the current is 0.6 A , then the internal resistance is 1/x ′ Ω. What is the value of x’?
