| Abstract: | A new method of measuring electromotive force and internal resistance of source using voltmeter instead of potentiometer was studied. The measurement result of electromotive force and internal resistance of source by voltmeter method was compared with that of potentiometer method. The result showed that the measurement result of voltmeter method was in very good agreement with that of potentiometer method. |
