A dielectric with a constant k = 4 and a thickness of b = 2 mm is inserted into a parallel strip capacitor having a surface area of A = 2.40 cm2 and a spacing of d = 4 mm as shown in the figure. The dielectric is placed right in the middle of the two pieces, the rest is filled with air. Specify: a. The equivalent capacitance of the capacitor after inserting the dielectric b. The ratio between the energy stored in the capacitor before and after insertion of the dielectric if given a potential difference of 10 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.
