Consider an isolated parallel-plate capacitor filled with air. Which of the following statements are True/False? Below Q and U are the charge and the energy stored on the capacitor, C is the capacitance, d is the distance between the plates and E is the electric field in the capacitor. When a dielectric material is inserted then the energy U decreases. True When the distance d increases then the electric field E increases as well. False The charge increases when a dielectric material is inserted. False When the distance d increases then the capacitance C increases as well. True When the distance d decreases then the charge Q stays the same. True When the distance d increases then the energy U increases as well. False The capacitance C increases when a dielectric material is inserted. False

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.
