NEET 2026 Physics Galvanometer and Ammeter MCQ Question

Type: MCQ-numerical-Medium-Class 12

A galvanometer of resistance 100 Ω gives full scale deflection for a current of 1 mA. It is converted into an ammeter of range 0 – 10 Å. The shunt required is:

A

0.01 Ω

B

0.10 Ω

C

1.0 Ω

D

0.001 Ω

Correct Answer

Option A

Detailed Explanation

The shunt resistance is calculated using the formula i_s r_s = i_G R_G. Substituting the given values, the shunt resistance r_s is found to be 0.01 Ω.
