摘　　要：电表在测量中有广泛的应用,因此如何了解电表和使用电表就显得十分重要。电流计是用来测量微小电流的,允许通过的电流很小,本文用它来扩大量程。Ammeter has a wide range of applications in the measurement. How to understand and use the ammeter are very important. Amperemeter is used to measure small currents, and the currents allowed to pass it are very small. In this paper, amperemeter is used to extend measurement range.
