| Abstract: | Applied the small measurement scale of a millivolmeter and based on the even-value interchangeability between voltage and current on a given unit resistor,infer conversely U 0 and U 0′Applied the above-mentioned formula as well as correspondent values of a payload resistor.Judging by the results from measurement and calculation,the improved measurement is characterized by high precision and less demand for measurement instrument.As a result of this,this new method will meet the demand for practicality and precision. |
