A parallel plate capacitor in air has a plate separation of 1.5 cm and a plate area of 25 cm^2. The plates are charged to a potential difference of 250V and disconnected from the source. The capacitor is then immersed in distilled water. (a) Determine the charge on the plate after immersion. (b) Capacitance and potential difference after immersion and (c) The change in the energy of the capacitor.
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.
