Joule Principle,t the day and perceive climate changes caused by variations in atmospheric pressure and temperature. We notice that the fire is the most striking manifestation of the daily thermal processes. We learn that it can be used to heat water and make it boil and discover its enormous potentiality to generate motion and useful work.

Dielectrics,of an electric field acquires an electric polarization that disappears when the field is removed. For small values of the applied electric field ., the polarization (electric dipole moment per unit volume) of an ordinary dielectric is proportional to the field, that is, . where . is the constant of proportionality.
