So the EMF \(E\) of a cell is equal to the sum of its terminal potential difference, \(V_{tpd}\), and the lost volts, \({V_L}\). This gives rise to the equation ... internal resistance and the load.

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 ... when the load resistance, \(R ...
