MHT CET 2024 Physics question
When a resistance of 100 is connected in series with a galvanometer of resistance G, its range is V. to double its range a resistance of 1000 is connected in series. The value of G is
Answer: (B)
Solution
A galvanometer of resistance with series resistance reads full scale when flows, so its voltage range is . With : . For double the range with : . Dividing, $2(G + 100) = G +
