A parallel-plate capacitor with plate area A = 0.14 m2 and plate separation d = 0.25 mm is connected to a 3.5-V battery. a) Determine the charge on the capacitor, the electric field, the capacitance, and the energy stored in the capacitor. You disconnect the battery, such that the capacitor remains charged. b) A slab of plastic with dielectric strength K=2.3 is placed between the plates of the capacitor, so that the gap is completely filled with the dielectric. What are the new values of the charge, electric field, capacitance, and energy stored in the capacitor?
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.
