under what conditions do ethers from oxonium salts?

Two cells, whose e.m.f.'s are same are connected in series. Their internal resistance are r_1 and r_2 respectively and r_1gtr_2 . When this combination is connected with an external resistance R then potential difference between the terminals of first cell becomes zero. The value of resistance R will be
