    s = (Ig×G)/(I-Ig)....s=shunt resistance , Ig=full scale deflection , G=resistance of galvanometer , I=new range of ammeter...

    Since Galvanometer is a very sensitive instrument...... therefore it can't measure heavy currents..... In order to convert a Galvanometer into an Ammeter, .....a very low resistance known as "shunt" resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt....
