(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

At a given instant, a 3.8 A current flows in the wires connected to a parallel-plate capacitor. What is the rate at which the electric field is changing between the plates if the square plates are 1.76 cm on a side?

2. Relevant equations

3. The attempt at a solution

I don't really know where to start...

Could you use the change in length=perm of free space(I +E(sub o)*Change in E) ? I don't know if this is even an equation..
