The terminals of a cell are cnnected to resistance R and the falll of potential across R is balaced against the fall of potential on a potentiometer wire.When R is 20 `Omega` and 10 `Omega` respectively, the corresponding lengths of potentiometer wire are 1.5 m and 1.2 m Claculate the internal resistance of the cell
