Consider a cloud to be one plate of a large capacitor and the earth below to be the other plate. Estimate the voltage between the cloud and earth if the cloud has a charge of -50 C (the earth below has an equal positive charge), is 2 km above the earth, has an area of 5 km x 5 km, and is separated from the earth by dry air.
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.
