I take an air-filled parallel-plate capacitor and connect it to an 18-v battery. It has a plate area 18 cm2 and a capacitance of 4 pF. After it is fully charged, I remove the battery. What is the energy density in the space between the plates? A) .00007 J/m3 B) .00009 J/m3 C) .000039 J/m3 D) none of these.
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.
