Electromagnetic Waves Part 1

The displacement current of 4.425µA is developed in the space between the plates of parallel plate capacitor when voltage is changing at a rate of 106Vs−1. The area of each plate of the capacitor is 40cm2. The distance between each plate of the capacitor is x×10−3m. The value of x is_____
(Permittivity of free space, E0=8.85×10−12C2N−1m−2 ).
