The Measurement of Internal Resistance and Current Constant for Sensitive Galvanometer
Hongying Li · Journal of Changchun Normal University · 2010
There are many methods to measure internal resistance and current constant for sensitive galvanometer.According to the circuit types,we classify it into divided voltage measurement and current limiting measurement.In this paper,we analyze and compare the two measurements,and draw a conclusion that the accuracy of divided voltage measurement is higher.In addition,the simple calculation of divided voltage measurement is given out.
