NEET Physics (general) MCQ Question
Type: MCQ-fact-Hard-Class 12
What is the primary function of a shunt resistance in a galvanometer?
A
To convert it into an ammeter by allowing a portion of the current to bypass the galvanometer.
B
To increase the sensitivity of the galvanometer to detect smaller currents.
C
To reduce the internal resistance of the galvanometer for more accurate measurements.
D
To measure alternating current effectively without any loss.
Correct Answer
Option A
Detailed Explanation
A shunt resistance is introduced in parallel with a galvanometer to convert it into an ammeter, allowing most of the current to bypass the galvanometer while a small fraction passes through it for measurement.
