A straight line plot showing the terminal potential energy (V) of a cell as a function of current ( I) drawn from it , is shown in the figure . Using this plot determine (i) the emf and (ii) internal resistance of the cell.
dear student,
equation of graph is
emf is when current is zero
therefore emf is 1.4V
internal resistance is magnitude of slope hence 5ohm
