The circuit above can be used to measure the emf, e, and the internal resistance of a source, r, by measuring the current, I, in the circuit, as a function of the external resistance, R. Student A does the experiment with a cell of emf ε = 1,5 V and internal resistance r = 100 12. Student B does the experiment with a cell of emf ε = 3,0 V and internal resistance r = 200 12. When the graphs of 1/1 vs R are plotted on the same set of axes, which of the options above gives the correct graphs for the experiments? (d) O (f) O (c) (6) (c)
