Question

Plot a graph showing variation of voltage vs the current drawn from the cell. How can one get information from this plot about the emf of the cell and its internal resistance?
Two cells of emf’s E₁ and E₂ and internal resistance r₁ and r₂ are connected in parallel. Obtain the expression for the emf and internal resistance of a single equivalent cell that can replace this combination?
