a certain capacitor has a capacitance of 4 uf when its plates are separated by 0.2 mm of vacant space.A battery is used to charge the plate to a potential difference of 500 V and is then disconnected from the system. a.) what will be the potential difference accross the plates if a sheet of mica 0.2 mm thick is inserted between the plates? b.) what will the capacitance be after the dielectric is inserted? c.) what is the permittivity of mica?
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.
