Electrostatic Potential and Capacitance

Electrostatics of Conductors, Dielectrics and polarization


Inside a conductor, electric field is zero. At the surface of a charged conductor, electric field must be normal to the surface at every point. The interior of a conductor can have no excess charge in the static situation. Electric potential is constant throughout the volume of the conductor and has the same value on its surface. Electric field at the surface of a charged conductor

\overrightarrow{E} = \frac{\sigma}{\varepsilon_{0}} \hat{n}

Dielectrics: Dielectrics are non conducting substances. In contrast to conductors, they have no charge carriers.

Polarisation: The induced dipole moment developed per unit volume in a dielectric slab on placing it in an electric field is called polarisation. It is denoted by p. 

\overrightarrow{P} = \chi_{e} \overrightarrow{E}
