Two cells \(E_1\) and \(E_2\) having equal EMF '\(E\)' and internal resistances \(r_1\) and \(r_2\left(r_1>r_2\right)\) respectively are connected in series. This combination is connected to an external resistance '\(R\)'. It is observed that the potential difference across the cell \(\mathrm{E}_1\) becomes zero. The value of '\(R\)' will be
