A parallel-plate capacitor has plates with anarea of 0.012 m2 and a separation of 0.88 mm. The space betweenthe plates is filled with a dielectric whose dielectric constant is 2.0.(a) What is the potential difference between the plates when thecharge on the capacitor plates is 4.7 mC? (b) Will your answer topart (a) increase, decrease, or stay the same if the dielectric constant is increased? Explain. (c) Calculate the potential differencefor the case where the dielectric constant is 4.0
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.
