PPT-Thermodynamic relations for dielectrics in an electric field

Section 10 Basic thermodynamics We always need at least 3 thermodynamic variables One extrinsic eg volume One intrinsic eg pressure Temperature Because of the equation of state only 2 of these are independent. We offer the widest selection of horse fencing, electric fences, polytapes, energizers, polyrope, fencing accessories and other equine products.
