Which instrument is specifically designed to detect and measure very small electric currents?

Explanation

A galvanometer is a sensitive instrument specifically designed to detect and measure very small electric currents, typically using the deflection of a small needle caused by the magnetic effect of the current passing through an internal coil. It served as an important foundation for the later development of other electrical measuring instruments, including the ammeter and voltmeter, which are essentially adapted versions of the basic galvanometer design. Galvanometers remain useful today in various sensitive scientific and laboratory measurement applications. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
