A displacement current of $\displaystyle 4.0$ A can be set up in the space between two parallel plates of $\displaystyle 6 \mu \mathrm{~F}$ capacitor. The rate of change of potential difference across the plates of the capacitor is nearly $\displaystyle \alpha \times 10^6 \mathrm{~V} / \mathrm{s}$. The value of $\displaystyle \alpha$ is $\displaystyle \_\_\_\_$.
