NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
In a diagram showing the conversion of a galvanometer to an ammeter, a shunt resistance r_s is connected in parallel to the galvanometer (G). What is the purpose of this shunt resistance?
A
To increase the range of the ammeter.
B
To decrease the sensitivity of the galvanometer.
C
To allow more current to pass through the galvanometer.
D
To protect the galvanometer from high voltage.
Correct Answer
Option A
Detailed Explanation
The shunt resistance r_s is used to increase the range of the ammeter by allowing most of the current to bypass the galvanometer, preventing it from being overloaded.
