Consider the Earth and a cloud layer 1000 m above the planet to be the plates of a parallel-plate capacitor. (a) If the cloud layer has an area of 3.0 km2 = 3000000 m2, what is the capacitance? ________________________F (b) If an electric field strength greater than 3.0 ✕ 106 N/C causes the air to break down and conduct charge (lightning), what is the maximum charge the cloud can hold? ________________________C

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.
