An air capacitor is made from two flat parallel plates 1.50mm apart. The magnitude of charge on each plate is 0.0180µC when the potential difference is 200 V. a) What is the capacitance? b) What is the area of each plate? c) What maximum voltage can be applied without dielectric breakdown? (Dielectric breakdown for air occurs at an electric-field strength of 3.0 x 106 V/m ) d) When the charge is 0.0180 µC, what total energy is stored?
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.
