A dielectric slab is slowly inserted between the plates of a parallel plate capacitor while the capacitor is connected to a battery. As it is being inserted: the capacitance and the charge on the plate increase but the potential difference between (A) the plates remains the same the capacitance and the charge on the positive plate decrease but the potential difference B between the plates remains the same the potential difference between the plates increases, the charge on the positive plate decreases, and the capacitance remains the same the capacitance, the potential difference between the plates, the charge on the positive plate D all decrease

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.
