Transient Method of Measuring Very Low Conductivities without Contacting Electrodes

An experimental procedure is proposed, which amounts to Fourier transforming the frequency depending torque in the Ogawa's torsion pendulum method. This reduces by a factor of the order 100 the fairly long times needed for measuring the very low conductivities of insulating materials.
