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.

of thickness d and dielectric constant k is introduced
between the plates while the battery remains con-
nected to the plates. (a) Show that the ratio of energy
stored after the dielectric is introduced to the energy
stored in the empty capacitor is U/U, = K. (b) Give a
physical explanation for this increase in stored energy.

This situation is not the same as in Example 26.5, in
which the battery was removed from the circuit before
the dielectric was introduced.
