In sea water at a frequency ν = 4 × 108 Hz, which has a permittivity ε ≈ 80 εo, permeability µ ≈ µo, and resistivity ρ = 0.25 Ω–m, a parallel plate capacitor is immersed and driven by an alternating voltage source V(t) = Vo \sin (2π νt). What fraction of the conduction current density is the displacement current density?
