1. The problem statement, all variables and given/known data
For copper we find that J=\sigmaE , where \sigma has the value 5.8x10^7 mksc units. If an alternating electric field represented by E0ei\omegat exists within the copper. Find the ratio of the conduction to the displacement current density at a frequency of 1megacycle/sec.
2. Relevant equations
J=\sigma dE0/dt
3. The attempt at a solution
So I'm hoping this is a straight forward as I'm making it out to be, minus my own issues with the units. I think it follows like this, but it seems too easy!
Please excuse my tex failures below...
J=\sigma dE0/dt = i\omega\sigmaE0
\omega\sigmaE0=E0/J = 1.04x10^12
