2020年5月27日 · Is there any reason the charge density would generally be uniform across the surface? We know: $$\sigma = \Delta E \cdot \varepsilon_0 \cdot \hat{n}$$ But what physically ensures the electric field just outside the conductor is equal in magnitude all around the encompassing circle?

2022年4月24日 · Describe the electric field inside the conductor, at the surface of the conductor, and outside the conductor as a result of the unbalanced charge. Describe the distribution of the charge in and on the conductor.

2025年1月22日 · Electric field at a point outside the shell. For a point outside the cylindrical shell, the Gaussian surface is the surface of a cylinder of radius \(r > R\) and length \(L\) , as shown in Figure \(\PageIndex{10}\). The charge enclosed by the Gaussian cylinder is equal to the charge on the cylindrical shell of length \(L\) .

The experimental proof of the presence of the electric field outside a current carrying wire can be achieved by measuring the voltage between any two points along the wire. Non zero voltage will be a proof of the existence of the electric field.

As you're probably aware, the crucial distinction between the two cases you mention is that when there's a conductor behind the sheet of charge, the electric field behind the sheet is zero since in the context of electrostatics, the electric field inside of a conductor vanishes.

A clever way to calculate the electric field from a charged conductor is to use Gauss' Law, which is explained in Appendix D in the textbook. Gauss' Law can be tricky to apply, though, so we won't get into that.

Free charges in a conductor also affect the direction of the electric field outside the conductor, as described here.-----Gauss's Law Playlist - https://www....

The electric field is zero inside a conductor. Just outside a conductor, the electric field lines are perpendicular to its surface, ending or beginning on charges on the surface. Any excess charge resides entirely on the surface or surfaces of a conductor.

Electric Fields are Perpendicular to Charged Surfaces. A second characteristic of conductors at electrostatic equilibrium is that the electric field upon the surface of the conductor is directed entirely perpendicular to the surface. There cannot be a component of electric field (or electric force) that is parallel to the surface.
