Air has a value of 1.00059, which is slightly higher than the value for a vacuum, whose value of 1 is the smallest possible.
Its value for various substances include 2.25 for paraffin, 78.2 for water, and about 2,000 for barium titanate. Air has a value of 1.00059, which is slightly higher than the value for a vacuum, whose value of 1 is the smallest possible. Identical to permittivity in the cgs system, it is symbolized by the Greek letter kappa, and is usually calculated by taking C over C naught. FTP, what is this constant, the measure of the increase in effectiveness of a capacitor when filled with an insulating material?
