We say the aluminum has a higher resistivity . In a conductor the current and current density are proportional to the applied electric field. The raindrop analogy helps us see this. The terminal speed (downward drift speed) of a raindrop is

WebIn electrical wiring, the maximum current density (for a given temperature rating) can vary from 4 A⋅mm −2 for a wire with no air circulation around it, to over 6 A⋅mm −2 for a wire in free air. Regulations for building wiring list the maximum allowed current of each size of cable in differing conditions. WebFeb 13, 2024 · The electrical current used in circuits is the current density based on the traversed area: $$ I = \int \vec j_{el} \cdot d\vec A$$ As you can see, the electrical current density is indeed something like the rate of flow of charge, but there is also the particle density. If the electrons slow down somewhere the current density stays the same ...
