Conductors, Electrostatics, Electric Field, Electric Potential, Examples – Physics

This video covers a tutorial on electrostatics with conductors, including whether they are positively or negatively charged, and electrostatic shielding. The three results are that the electric field inside a conductor is zero, excess charge resides on the surface, and the electric field just outside conductor is perpendicular to the surface.
