Question

Potential difference across terminals of a
cell were measured (in volts) against different currents ( in
ampere) flowing through the cell A graph was drawn which has a
straight line ABC Using the data given in the graph determine,
(I) the emf and
(ii) the internal resistance of the cell

emf=1 4
v=e-ir ==> r=(e-v)/i=(1 4-1 2)/0 04=5
