A certain parallel-plate capacitor consists of two plates, each with area 200 cm2 , separated by a 0.4 cm air gap. a) Compute its capacitance. b) If the capacitor is connected across a 500 V source, find the charge on it, the energy stored in it, and the value of E (electric field) between the plates. c) If a liquid with K=2.60 is poured between the plates so as to fill the air gap, how much additional charge will flow onto the capacitor from the 500 V source?
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.
