    In an experiment, a graph was plotted of the potential difference V between the terminals of a cell against the circuit current i by varying load rheostat. Internal conductance of the cell is given by

    A)             xy  

    B)             \[\frac{y}{x}\]

    C)             \[\frac{x}{y}\]                                

    D)             (x ? y)

    Correct Answer: B

    Solution :

                Here internal resistance is given by the slope of graph i.e. \[\frac{x}{y}\]. But conductance \[=\frac{1}{\text{Resistance }}=\frac{y}{x}\]
