The electric potential energy of a charged object depends on the voltage it is subjected to by E=QV where Q is the charge on the object in Coulombs (C) and V is the voltage in volts. Suppose that during a storm, the potential difference between a storm cloud and the ground below is 33×106 volts and the amount of charge held in the storm cloud, just before a lightning strike occurs, is 15 C. How much energy is transferred to the ground when the lightning strikes?
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.
