As shown in the video, to find the EMF and internal resistance of a cell, the following circuit is set up. At the point at which the line meets the terminal potential difference axis there is no ...

The internal resistance of lithium-ion cells is an important measurement to make because the cell’s internal resistance can determine the suitability of the cell for a particular application.

Measurement of circuit's attenuation factor and generator's internal resistance leads to r c, the capacitor's ESR: Instead of using a sine wave excitation, we can use a square wave.
