Objective. To measure the internal resistance of a given primary cell using potentiometer. Theory Potentiometer. Potentiometer is a device used to measure the internal resistance of a cell, to compare the e.m.f. of two cells and potential difference across a resistor.... It is practically difficult to measure the internal resistance of a 12V battery as it is too low to measure using conventional methods, The values given by the manufacturer is best for using for any computation. or use a load to measure the 2 voltage drops 1. across the load and 2. total voltage

**To Determine The Internal Resistance of a Given Primary**

3/02/2012 · If I have a good estimate of the internal resistance when the battery is fully drained, I can predict the circuit behavior when the 2nd battery is added. Thanks! D. Diver300 Well-Known Member. Feb 2, 2012 #2. Feb 2, 2012 #2. You don't have to worry about the resistance of the power supply in that situation, because it is in current limit. I guess that you are sure that the current is 50 A with how to find specific file on google pixel The internal resistance show how the voltage will drop when the battery is loaded. The slope of the yellow line is the internal resistance of the battery in the above chart. I.e. the single number, that is the internal resistance, can show the same as the above chart.
