उत्तर
The given sentence is right.
Explanation:
A galvanometer is a highly sensitive instrument specifically designed to detect and measure the presence, direction, and magnitude of small electrical currents. While it is often modified into an ammeter or voltmeter to measure larger currents or voltages, it is fundamentally a tool for electrical measurements.
