Which of the following pair of devices measure the same physical quantity?
Updated On: Apr 7, 2025
- Ammeter, voltmeter
- Ammeter, galvanometer
- Galvanometer, voltmeter
- Ammeter, battery
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
An ammeter is a device used to measure electric current in a circuit.
A galvanometer is a sensitive instrument that detects and measures small currents.
Therefore, both ammeter and galvanometer measure the same physical quantity, i.e., electric current.
Note: While the ammeter measures larger currents and is used in series in circuits, the galvanometer is used for detecting smaller currents with high sensitivity.
The correct option is (B): Ammeter, galvanometer
