How is current uniformly distribute in dc line?

In a direct current (DC) line, current is uniformly distributed when the line has a consistent cross-sectional area and material properties along its length. This uniform distribution occurs because, in a DC circuit, the current is steady and does not fluctuate, allowing charge carriers to flow evenly. Additionally, any resistive losses in the line should be minimal to maintain a uniform current distribution. However, in practical scenariOS, factors like temperature and resistance variations can lead to slight deviations from perfect uniformity.
