| Abstract: | The capacitive formula of the local field derived from the electric axis method in field theory provides a close theoretical basis for the design of capacitance transducer in the precision measurement. Besides electric power and dispatch transmission the results find the new application for the classical electric axis method. Presents the comparison between each value of approximate computation and that of the exact one. |
