13. A capacitor is formed of two 1 mm thick parallel plates that are separated by 2 mm. An identical metal plate is now carefully inserted between the two plates so that a space of 0.5 mm is left on either side of the new plate, as shown below. When the metal plate is inserted the capacitance a. decreases. 1 mm b. increases. 2 mm] 1 mm 1 mm

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.
