MHT CET 2026 Physics question
A galvanometer has a current range of 10 mA and a voltage range of 0.75 V. To convert this galvanometer into an ammeter of range 10 A, what is the shunt resistance?
Answer: (D)
Solution
The current range mA A and the voltage range V mean that full-scale deflection occurs when the voltage across the galvanometer is V, so . For an ammeter of range A, a shunt in parallel must carry , with $ G = (I -
