NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): A shunt resistance is used to convert a galvanometer into an ammeter. | Reason (R): The shunt resistance allows the galvanometer to measure larger currents than it could handle alone.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
The shunt resistance, being of very small value, is connected in parallel with the galvanometer, allowing most of the current to bypass the galvanometer, thus enabling it to measure larger currents.
