Question 220Electricity & Electronics - 1st Asst/Chief

The correct answer is C) very small amounts of current. A galvanometer is an instrument used to measure very small amounts of electric current flowing in a circuit. It works by detecting the deflection of a pointer or needle within the instrument, which is proportional to the amount of current passing through it. This makes it well-suited for measuring small currents that would not be easily detected by other instruments. The other options are incorrect because a galvanometer is not used to measure the thickness of galvanized metal (A), the quantity of galvans (which is not a standard unit) in a circuit (B), or the resistance of electrical wiring insulation (D). Those measurements require different types of electrical instruments.
