    What is measured by Ammeter?

    A galvanometer of resistance 50Omega is converted into an ammeter by connecting a low resistance (shunt) of value 1Omega in parallel to the galvanometer, S. If full - scale deflection current of the galvanometer is 10 mA, then the maximum current that can be measured by the ammeter is -

    If the galvanometer current is 10 mA, resistance of the galvanometer is 40 Omega and shunt of 2 Omega is connected to the galvanometer, the maximum current which can be measured by this ammeter is

    An ammeter consists of a galvanometer of a resistance 45 Omega shunted with a resistance of 3 Omega . If the current rating of that can be measured by the ammeter will be
