NEET Physics Galvanometer as Ammeter MCQ Question
A galvanometer of resistance 100 Ω gives full scale deflection for a current of 1.0 mA. It is converted into an ammeter of range 0-1 Å. The resistance of the ammeter will be close to
0.1 Ω
0.8 Ω
0 Ω
10 Ω
Correct Answer
Detailed Explanation
To convert the galvanometer to an ammeter, a shunt resistor is used. The shunt resistance is calculated using the formula R_shunt = (I_g * R_g) / (I - I_g).
