Intuitively it fails in making an equivalence to area which is an unrelated dimensional unit, as two lengths multiplied together equaling resistance, as well as the skin-effect related to Intensity/Current which is why insulation/isolation of wires are incredibly important.

The classical approach used charge diffusion iirc, and you can find classical examples of this in Oliver Heaviside's published works (archive.org iirc). He's the one that simplified Maxwell's 20+ equations down to the small number we use today.
