A parallel plate capacitor, in which the space between the plates is empty, has a capacitance of Co=987 µF and it is connected to a battery whose voltage is V=35 V and fully charged. Once it is fully charged, it is disconnected from the battery and without affecting the charge on the plates, space between the plates is filled with a dielectric material of K = 9.9. How much change occurs in the energy of the capacitor; final energy minus initial energy? Express your answer in units of mJ (milli Joules) using zero decimal places.
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.
