Seawater at a frequency f = 9 × 102 Hz, has permittivity ε = 80ε0 and resistivity ρ = 0.25 Ωm. Imagine a parallel plate capacitor is immersed in seawater and is driven by an alternating voltage source V(t)=V0 sin (2πft). Then the conduction current density becomes 10x times the displacement current density after time t = \(\frac 1{800}\) s. The value of x is .........
