Hello all. I have been looking at this problem: I wrote three equations there, one for each part, which I think will help me solve each part; is my approach to the problem using those equations that you see there correct? I am just looking for some advice on where and how to start this problem. It looks like to me that I cannot calculate the velocity of the electrons until I get the volume charge density and current density between the two electrodes? To help you help me, here are some notes pertaining to this problem, but I have no similar examples to go off of. Any and all help is greatly appreciated.
