13. Considering a parallel-plate capacitor, which of the following is true? If it is fully charged, the electric field inside the capacitor is zero, which is the reason why a capacitor acts as an open circuit when fully charged. If it is fully charged, the potentials on each plate are always equal in magnitude but opposite in polarity. If it is fully charged, the surface charge densities on each plate are always equal in magnitude but opposite in polarity. The answer can be found on more than one of the other choices.
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.
