A parallel plate capacitor has a capacitance of 2.0 nF. The capacitor is initially charged such that the potential difference between the plates is 100 V with a dielectric between the plates of ruby mica (κ = 5.4). The capacitor is then disconnected from the power source. a) How much work must be done to remove the ruby mica sheet? b) Determine the potential difference between the plates after the ruby mica sheet has been removed.
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.
