Unsure of how to approach this type of problem—Current densities in wires

[QUOTE="The Blind Watchmaker, post: 5952797, member: 641934"] [h2]Homework Statement [/h2] [ATTACH=full]221386[/ATTACH] [ATTACH=full]221387[/ATTACH] [h2]Homework Equations[/h2] J = nqv[SUB]d[/SUB] J = I/A Q = It [h2]The Attempt at a Solution[/h2] Basically we check whether the variable that we are looking at is proportional or inversely proportional. However, at what part do we stop? Where is it okay to substitute say Q = It and where is it not? I am getting confused on this one. Also, are there other forms of the velocity drift formula? Or is it strictly limited to v[SUB]d[/SUB] = J/(nq) = I/(Anq) ? Thank you! :) [/QUOTE]
