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 particle…

Chapter 21, Problem 88MSPP

A Lightning Strike

Storm clouds build up large negative charges, as described in the chapter. The charges dwell in charge centers, regions of concentrated charge. Suppose a cloud has –25 C in a 1.0|dash|km|dash|diameter spherical charge center located 10 km above the ground, as sketched in Figure P21.86. The negative charge center attracts a similar amount of positive charge that is spread on the ground below the cloud.

Chapter 21, Problem 88MSPP, A Lightning Strike Storm clouds build up large negative charges, as described in the chapter. The

The charge center and the ground function as a charged capacitor, with a potential difference of approximately 4 × 10⁸ V. The large electric field between these two "electrodes" may ionize the air, leading to a conducting path between the cloud and the ground. Charges will flow along this conducting path, causing a discharge of the capacitor-a lightning strike.

What is the approximate capacitance of the charge center +ground system?

A. 6 × 10^–8F

B. 2 × 10⁷ F

C. 4 × 10⁶ F

D. 8 × 10⁶ F
