A teaching assistant builds a parallel-plate capacitor with adjustable spacing between the plates. When the plates are at their initial separation, the capacitance is 5.00 µF. (a) At this capacitance, the capacitor is connected to a 12.00 V battery. After fully charging, how much energy (in µJ) is stored in the capacitor? µJ (b) The battery is then disconnected. Without discharging the capacitor, the teaching assistant then doubles the separation between the plates. At this point, how much energy (in µJ) is stored in the capacitor? µJ (c) Without changing this new separation between the plates, the capacitor is discharged, and then reconnected to the 12.00 V battery. Now, after fully charging, how much energy (in µJ) is stored in the capacitor? µJ

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.
