A galvanometer with a coil resistance of `100Omega` shows a full-scale deflection when a current of 1 mA is passed through it. What is value of the resistance which can convert this galvanometer into an ammeter showing a full scale deflection for a current 10 A? A resistance of the required value is available but it will get burnt if the energy dissipated in it is greater then 1 W. Can it be used for the conversion of the galvanometer described above?
