Electric diffusion in cylindrical conductors from an extended irreversible thermodynamics perspective

► Inertial effects on electric diffusion are explored in cylindrical conductors. ► When the field penetrates in the conductor, the inductance is minimum at a critical radius. ► For aluminum, the minimum inductance is 22.1 fH at the critical radius of 35.1 nm. ► This shows the importance of inertial effects at the nanoscale. ► The results presented here may be relevant in nanophotonics.
