A parallel plate capacitor is completely immersed in a liquid of resistivity $0.25 \Omega \mathrm{m}$ and relative permittivity 80 . If the plates of the capacitor are connected to an alternating voltage source of $\mathrm{V}_0 \sin (\omega \mathrm{t})$ volt at a frequency of $0.4 \mathrm{GHz}$, then the ratio of the amplitudes of the displacement current and conduction current is ____
