A capacitor consists of two square metal plates, each measuring 5x10-2m on a side. In between the plates is a sheet of mica measuring 1x10-4m thick. (a) What is the capacitance of this capacitor? If the charge in one plate is 2x10-8C, what is the (b) potential difference and (c) electric field between the plates? (Hint: C = ε A/d ; A for Area; and V = q/C; E = V/d)
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.
