Permittivity of a Lossless Material From a Capacitance Measurement

  1. Place three samples (air, Teflon, glass) between the aligned and polished ends of two 3/8" diameter, 1/2" lengths of 6061 Al rods. Measure the capacitances and from the known surface area and spacing determine the material's relative permittivity..
