NEET 2014 Physics Ammeter and Voltmeter MCQ Question
Type: MCQ-numerical-Medium-Class 12
In an ammeter 0.2% of main current passes through the galvanometer. If resistance of galvanometer is G, the resistance of ammeter will be
A
1/499 G
B
1/500 G
C
G
D
499 G
Correct Answer
Option D
Detailed Explanation
The shunt resistance S is given by S = G/(n - 1), where n is the ratio of total current to galvanometer current. Here, n = 1/0.002 = 500, so S = G/499, making the total resistance 499 G.
