Consider a parallel square-plate capacitor in vacuum being charged by a battery. After charging, the battery was removed. The plate separation distance of the capacitor is reduced by a factor of 0.80 and is then inserted with a dielectric with a dielectric constant of 3.80. By what factor does its potential energy change? a. 0.17 b. 0.21 c. 0.26. d. 0.33
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.
