Fórmula
Cómo Funciona
The American Wire Gauge (AWG) system is a standardized method for specifying wire diameter and cross-sectional area used in electrical and telecommunications engineering. The AWG scale uses a logarithmic formula to calculate wire dimensions, with each step representing a precise reduction in wire diameter. This system allows engineers and electricians to precisely determine wire characteristics like diameter, cross-sectional area, electrical resistance, and current-carrying capacity.
Ejemplo Resuelto
Problem: Calculate the diameter, cross-sectional area, and current capacity for AWG 10 wire Solution: 1. Diameter (inches): d = 0.005 × 92^((36-10)/39) = 0.1019 inches 2. Diameter (mm): 0.1019 × 25.4 = 2.59 mm 3. Cross-sectional area: π(2.59/2)² = 5.27 mm² 4. Current capacity: 7 × (5.27)^0.726 ≈ 15.3 A
