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 ' ', its capacity will increase to ' ' times original current. The value of ' ' is
Answer: (D)
Solution
With a shunt across a galvanometer of resistance (full-scale current ), the total current is . The capacity becomes times, so , which gives . With the second shunt :
