In a potentiometer experiment it is found that no current passes through the galvanometer when the terminals of the cell are connected across 0.52m of the potentiometer wire. If the cell is shunted by a resistance of 5Ω balance is obtained when the cell connected across 0.4 m of the wire. Find the internal resistance of the cell.

A moving coil galvanometer has 50 turns and each turn has an area 210 . The magnetic field produced by the magnet inside the galvanometer is 0.02 . The torsional constant of the suspension wire is 10 . When a current flows through the galvanometer, a full scale deflection occurs if the coil rotates by 0.2 . The resistance of the coil of the galvanometer is 50 . This galvanometer is to be converted into an ammeter capable of measuring current in the range 01.0 . For this purpose, a shunt resistance is to be added in parallel to the galvanometer. The value of this shunt resistance, in , is __________.
