A metal sphere with radius R is wrapped with a uniform dielectric layer, as shown in the figure on the right, and its radius is R1. Suppose the relative permittivity of the dielectric is εr, and the amount of charge carried by the metal ball is Q, try to find: (1) the distribution of field strength in each region inside the dielectric layer and outside the dielectric layer; (2) the electric potential of the metal ball.
Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
