357317 A potentiometer circuit has been set up for finding the internal resistance of a given cell. The main battery, used across the potentiometer wire, has an emf 2.0 \(V\) and a negligible internal resistance. The potentiometer wire itself is 4\(m\) long. When the resistance \(R\) connected across the given cell, has values of (1) infinity, (2)\(9.5\Omega \), the balancing lengths, on the potentiometer wire are found to be 3\(m\) and 2.85 \(m\) respectively. The value of internal resistance of the cell is
357318
In figure battery \(E\) is balanced on \(55\;cm\) length of potentiometer wire but when a resistance of \(10\,\Omega \) is connected in parallel with the battery then it balances on \(50\;cm\) length of the potentiometer wire then internal resistance \(r\) of the battery is :
