The two identical square plates of a parallel plate capacitor in vacuum have a separation distance of 0.050 mm so that the capacitance is measured as 0.870 nF. Suppose this capacitor is to be refashioned into a cylindrical capacitor instead. This is done by using one plate for the outer cylinder, while the other plate is stripped by removing a quarter length on one side with the remaining piece used to create the inner cylinder. What will be the capacitance of this cylindrical capacitor? a) 1.355 x 10-11 Farad b) 9.500 x 10-13 Farad c) 2.812 x 10-12 Farad d) 8.700 x 10-10 Farad

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.
