This quantity is the overall constant multiplying every component of a tensor denoted P that may be simplified by the Kleinman symmetry condition. Alpha is set equal to 3 over N times a rational function of two forms of this quantity in the Clausius–Mossotti formula. Electric susceptibility (15[2])is one less than a form (-5[1])of this quantity (15[1])that is also (15[2])known as the dielectric (15[2])constant. (15[5]0[1])Multiplying (15[3]-5[1])this quantity (15[1]-5[1])by the area (15[1])of two plates over the distance (15[1])between (15[2])them (15[2]10[1]-5[1])yields (15[1]-5[1])(*) capacitance. (10[1]-5[3])This quantity (10[2])is the constant of proportionality (10[1])between the E and D (-5[1])fields, and divides the enclosed (10[1])charge to produce electric (10[1])flux in Gauss’s (-5[2])law. (10[1]-5[2])In c·g·s units, this quantity (10[1])for a vacuum (10[1]-5[1])equals one over four pi, (10[2]-5[1])which sets Coulomb’s (10[2]-5[1])constant equal to one. (10[2])For 10 points, name this electric analog (-5[1])of permeability, (10[2])denoted (-5[1])epsilon. (10[4])■END■ (10[7]0[7])
