Reply to comment by pewpewbrrrrrrt in How does an ideal vacuum have a dielectric breakdown voltage of 10^12 MV/m? If there is nothing there, then how can electricity pass through it? by skovalen

You can shield against electric fields by using a faraday Cage. This is above highschool level but the wuick answer is that, using maxwells equations, you find the the electric potential inside such a cage is exactly 0 no matter what charges there may be outside the cage. And since the electric field is the gradient of the potential (again, sorry if that's too advanced for you) it is also 0.
