Terminal voltage Hence the graph between and will be a straight line having negative slope and positive intercept. Thermal power generated in the external circuit Hence graph between and will be a parabola passing through origin. Also at an instant, thermal power generated in the cell and total electrical power generated in the cell Hence the fraction so It means graph between and will be a straight line passing through origin |
