The electric field is zero everywhere inside a charged conductor in electrostatic equilibrium. Can you infer that the potential is everywhere zero (Yes/No)? Explain your answer.
Homework Answers
E = -(del V / del r) (1)
i.e electric field at any point is the negative of the gradient of the electric potential at that point.
If E in a charged conductor is zero, then from (1) it can be inferred that V= constant & the constant may not be zero.
For example, in case of a charged conducting sphere, the electric field inside the sphere is zero whereas the electric potential inside the sphere is constant and is equal to the electric potential on the outer surface of the sphere

The electric field must be zero inside a conductor in electrostatic equilibrium, but not inside an insulator. It turns out that we can still apply Gauss's law to a Gaussian surface that is entirely within an insulator by replacing the right-hand side of Gauss's law, Qin/ε0, with Qin/ε, where ε is the permittivity of the material. (Technically, ε0 is called the vacuum permittivity.) Suppose that a 75 nC point charge is surrounded by a thin, 32-cm-diameter spherical rubber shell and...
