SUMMARY
The discussion clarifies the role of current density (J) in wire conductors, emphasizing that while DC current is distributed throughout the wire, AC current primarily exists within the skin depth region. For copper conductors at 60 Hz, this skin depth is approximately 1 cm. The skin effect significantly influences the distribution of AC current, necessitating a deeper understanding of J in this context.
