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.
