| Abstract: | We designed an experimental apparatus of Simple millivolt level electromotive force to be measured and studied its stability. By changing the size of the resistor in the experimental apparatus to achieve change in output electromotive force,and the output of millivolt level electromotive force is very stable at each measurement point of the experiment instrument of potential difference meter. The experimental apparatus can satisfy the box-type potentiometer＇s measurement range and accuracy requirements,and the ancillary equipment of the experiment instrument of potential difference meter is ideal. |
