A battery charges a parallel-plate capacitor fully and then is removed. The plates are then slowly pulled further apart. What happens to the potential difference between the plates as they are being separated? [Hint: (1) the capacitance C decreases as d increases. (2) The charge Q is not affected by separating the plates further. (3) Use C = Q/V]
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.
