Question 324Electricity & Electronics - QMED

The correct answer is D) very small amounts of current. A galvanometer is a sensitive electrical instrument used to measure very small amounts of electric current. It works by detecting the deflection of a needle or pointer in response to the flow of current through a coil within the instrument. This makes it ideal for measuring small currents, which is why it is the correct choice for this question. The other answer choices are incorrect because a galvanometer is not used to measure the thickness of galvanized metal (A), the resistance of electrical wiring insulation (B), or the quantity of "galvans" (which is not a standard electrical term) in a circuit (C).
