MHT CET 2024 Physics question
When a galvanometer is shunted by a resistance 'S', its current capacity increases 'n' times. If the same galvanometer is shunted by another resistance S', its current capacity increase to n'. The value of n' in terms of n, S and S' is
Answer: (D)
Solution
With a shunt across a galvanometer of resistance , the main current is , so the current capacity becomes times when , giving . With shunt : $n'
