Where: σ is … In electrical wiring, the maximum current density (for a given temperature rating) can vary from 4 A⋅mm for a wire with no air circulation around it, to over 6 A⋅mm for a wire in free air. Regulations for building wiring list the maximum allowed current of each size of cable in differing conditions. For compact designs, such as windings of SMPS transformers, the value might be as low as 2 A⋅mm . If the wire is carrying high-frequency alternating currents, the skin effect may affect the distributio… svetsa aluminium med pinne https://boldnraw.com
