| Abstract: | A constant exciting current source used especially for physical experiment has been developed.The stability of the output current has been tested.Taking the experiment of surveying magnetic field intensity by Hall element for instance,we have comparatively tested the experimental data between the constant current source and the general voltage-stabilized power source.Results show that the output current stability can reach to 0.1%,and the experimental data linearity of the constant current source is highter... |
