Two conducting plates of equal area A are separated by a distance d by forming a parallel plate capacitor. When a potential difference of V is applied across the capacitor, a charge with magnitude Q is observed on the plates of the capacitor. When the following operations are carried out independently, write, with reasons, how the capacitance of the capacitor changes. a)Potential difference, V, is decreased b)A dielectric material is inserted between the plates of the capacitor.
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.
