Figure 25.5 (Example 25.2) A spherical capacitor consists of an inner sphere of radius a sur- rounded by a concentric spherical shell of radius b. The diagram shows the capacitor carrying a charge Q. The electric field between the spheres is directed radially outward when the inner sphere is positively charged. +Q
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.
