Web14 de mai. de 2024 · Artwork: An ammeter (A) is a sensitive instrument that measures only relatively small currents. If you want to measure bigger currents, you need to divert a high proportion of them around a "shunt" resistor (Ω). Since the meter and the shunt are in parallel, they have the same voltage across them. caons 東芝キヤリア
