The resistances of a galvanometer is 200 Omega and full-scale deflection is obtained for a current of 5mA. The galvanometer is connected with a source of electricity through a resistance of 58 Omega in series. The emf of the cell is 30V and its internal resistance is negligibly small .Find out the resistance of the shunt that should be connected with the galvanometer in parallel.

When a current of 5 mA is passed through a galvanometer having a coil of resistance 15Omega , it show full scale defelction. The value of the resistance to be put in series range 0.10v is

An electric cell is sending electric currents through a resistance of 10 Omega . IF a shunt of 1 Omega is connected with that resistance then the current through the 10 Omega resistance becomes half of the previous value.What is the resistance of the cell?IF the current through the shunt be 0.9A, then what will be the emf of the cell?
