1. The relative permittivity of a dielectric is 2.25. (a) What is its permittivity? (b) What will be the capacitance if this dielectric is inserted into a 7.8 uF air capacitor? 2. A parallel plate capacitor is made up of two plates, each having an area of 8.0x10-4 m2 and separated from each other by 5.0 mm. It is filled with equal thicknesses of dielectrics arranged as shown. What is its capacitance?
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.
