You make an air-filled parallel-plate Capacitor having a Capacitance of 272 pF [Co]. You connect your Capacitor to a 240.-V Battery [AV] 0 to charge the plates. Once charged, you disconnect the Battery, and then, place the Capacitor into a pail of water (K = 80).
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.
