A certain parallel-plate capacitor is filled with a dielectric for which K = 4.67. The area of each plate is 0.0225 m², and the plates are separated by 2.38 mm. The capacitor will fail (short out and burn up) if the electric field between the plates exceeds 172 kN/C. What is the maximum energy that can be stored in the capacitor? Number i Units
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.
Calculate the capacitance of capacitor.
Here, k is the relative permittivity, is the permittivity of free space, is the area of each plate and d is the distance between plates.
Put the known values and solve.
