A spherical capacitor has a total charge Q = 5 µC, is filled by a dielectric with dielectric constant 5. If the internal spherical shell has the radius a = 8 cm and the external spherical shell has the radius b = 10 cm. The energy (in mJ) stored in this capacitor is
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.
