Four Method in Measureing Electric Resistance with Box-type Potentiometer
YU Gui-fenga · Experiment Science and Technology · 2008
The experiment of potential difference meter is a classical experiment which adopts the method of voltage compensation. The method of measuring electric resistance with box-type potentiometer is introduced in the paper. Four variant circuits are designed which are compared in serviceability, influencing factor and applicability. This experiment shows that box-type potentiometer method has strong flexibility and can be a good choice for design-oriented experiment.
