Understanding 0.25 mm in AWG: A Guide to Wire Gauges
Introduction
When working with electrical wiring, understanding the different gauges of wire is crucial for ensuring the safety and efficiency of electrical systems. In the American Wire Gauge (AWG) system, wire gauges are measured in terms of their diameter, with smaller gauges indicating larger diameters. One commonly used wire gauge is 0.25 mm, which is equivalent to AWG 24. In this article, we will explore the characteristics and applications of 0.25 mm wire gauges in AWG.
What is AWG?
The American Wire Gauge (AWG) is a standard system used to measure the diameter of electrical wire. The AWG system is based on a geometric progression, where each gauge is approximately 1.122 times smaller than the previous one. The AWG system ranges from 0000 (53.5 mm²) to 40 (0.05 mm²), with larger gauges indicating smaller diameters.
Characteristics of 0.25 mm (AWG 24) Wire
Wire with a diameter of 0.25 mm is equivalent to AWG 24. This wire gauge has the following characteristics:
Diameter:
The diameter of 0.25 mm wire is, as the name suggests, 0.25 millimeters or 0.0098 inches.
Cross-Sectional Area:
The cross-sectional area of AWG 24 wire is approximately 0.51 mm² or 0.00079 in².
Resistance:
The resistance of AWG 24 wire is around 28.4 ohms per kilometer or 84.5 ohms per mile.
Current Carrying Capacity:
AWG 24 wire has a current carrying capacity of around 3.5 amps.
Applications of 0.25 mm (AWG 24) Wire
