Research on the Principle and Improvement of Kelvin Dripping-Water Charge Collector

The principle of Kelvin dripping-water discharge is analyzed, and the factors that affect the discharge are studied by experiments. The main factors and secondary factors are found and the discharge device is improved. The relationship between the conductivity of the solution and the discharge interval was studied by using different concentrations of NaCl solution, and the principle of Kelvin discharge experiment was further verified. The improved Kelvin dripping-water charge collector has greatly improved the stability of the experiment. The research is important for the manufacture of laboratory equipment and the demonstration of the experiment.
