Question:
The AC voltage across a resistance can be measured using a
The AC voltage across a resistance can be measured using a
Show Hint
For AC voltage measurement across resistors, a calibrated moving coil galvanometer (with rectification) is often used.
Updated On: Apr 15, 2025
- hot wire voltmeter
- moving coil galvanometer
- potential coil galvanometer
- moving magnet galvanometer
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
A moving coil galvanometer works on the principle of detecting current and voltage in circuits. When rectified or suitably modified, it can measure AC voltages across resistors.
Other types such as hot wire voltmeters are suitable but more commonly used for high-power applications.
