An electromagnetic wave of frequency $\displaystyle 100$ MHz propagates through a medium of conductivity, $\displaystyle \sigma=10 \mathrm{mho} / \mathrm{m}$. The ratio of maximum conduction current density to maximum displacement current density is $\displaystyle \_\_\_\_$. $$\left[\text { Take } \frac{1}{4 \pi \epsilon_0}=9 \times 10^9 \mathrm{Nm}^2 / \mathrm{C}^2\right] $$
