In this video, we use Gauss’s law to find the electric field of a uniformly charged sphere. We derive the field both inside and outside the sphere, explain the symmetry behind the Gaussian surface ...

This video provides an essential cheat sheet covering electric fields and electric potential. Key formulas, concepts, and relationships are summarized clearly, with practical tips for ...

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...

image: The PCN could grow on the surface of SrTiO3 by the formation of the N-Sr bond, which could generate the lamination effect ignited by the built-in electric field modulation. This could be ...
