References

Etymology and History:

The word "ammeter" originated in the 19th century from the combination of "ampere" (named after André-Marie Ampère, a French physicist) and "meter," derived from the Greek "metron" meaning measure. It evolved during the Industrial Revolution as electrical engineering advanced, with the first practical ammeters developed in the late 1800s for telegraphy and power systems. In Thai, it was adopted through translations of Western scientific texts in the mid-20th century.

Literary References:

In scientific literature, "ammeter" appears in texts like Isaac Asimov's "Foundation" series, where it metaphorically represents technological precision (e.g., "The ammeter's steady needle confirmed the ship's power integrity"). In Thai contexts, it is referenced in educational books such as "Physics for Engineers" by Thai authors, where a passage states: "แอมมิเตอร์ช่วยให้เราเข้าใจกระแสไฟฟ้าได้ดียิ่งขึ้น" (The ammeter helps us understand electric current better), emphasizing its role in learning.
