A parallel-plate vacuum capacitor has 8.08 J of energy stored in it. The separation between the plates is 3.30 mm. Part A: If the separation is decreased to 1.80 mm, what is the energy now stored if the capacitor was disconnected from the potential source before the separation of the plates was changed? Part B: If the separation is decreased to 1.80 mm, what is the energy now stored if the capacitor remained connected to the potential source while the separation of the plates was changed?
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.
