When a voltage of 250 V is applied across the plates of a parallel plate capacitor 7.5 × 10−7 C of charge accumulates on the plates of that capacitor. (a) What is the capacitance of this capacitor? (b) If the distance between the plates is 5 × 10−5 m, what is the surface area of the plates? (c) How much energy will the capacitor store at this time?
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.
