There's a few minerals that exhibit something called piezoelectricity and pyroelectricity, which mean that either heat or pressure can turn them electric. Here's a demo from the SciShow Rocks Box where you can see this for yourself - all...

How do main electrical panels work. Learn the main parts of electrical panel, load center, service panel in this video.

First we solve for the electric potential along the axis of a uniform thin ring of electric charge. Then we use that electric potential to solve for the electric field at the same location.

This video shows how to prove that the electric field outside a uniformly charged sphere is the same as if the charged sphere were a point particle. Using Gauss' law, the electric field is shown to be constant and dependent only on the...
