| Abstract: | The laboratory instruments,experimental circuits and experimental methods are suggested to be improved aiming at problems in experiment.Digit voltmeters displaying positive or negative electric charge,are advised to be adjus- ted roughly or precisely to measure value of potential difference.The principle of regulation makes the adjustment of bridge equilibrium simple,visual and easy. |
