A parallel-plate capacitor has square plates of side s = 2.30 cm and plate separation d = 3.00 mm. The capacitor is charged by a battery to a charge Q = 4.50 µc, after which the battery is disconnected. A porcelain dielectric (x = 6.5) is then inserted a distance y = 1.00 cm into the capacitor (see figure below). Hint: Consider the system as two capacitors connected in parallel. Dielectric K (a) What is the effective capacitance of this capacitor? pF (b) How much energy is stored in 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.
