A pair of conducting plates is oppositely charged, such that the positive plate carries 3C of charge. When the plates are in a vacuum, the potential difference between them is 5V. However, when a piece of glass is inserted to fill the gap in between the plates, the potential difference is 30V. What is the dielectric constant of the glass?
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.
