A galvanometer of resistance `R_(G)` is to be converted into an ammeter, with the help of a shunt of resistance R. If the ratio of the heat dissipated through galvanometer and shunt is 3:4, then

When a galvanometer of resistance G iws converted into an ammeter of range IA then the current passing through shunt (S) is

A galvanometer of resistance 70 Omega , is converted to an ammeter by a shunt resistance r_(3) = 0.03 Omega . The value of its resistance will become

A galvanometer of resistance 70 Omega , is converted to an ammeter by a shunt resistance r_(3) = 0.03 Omega . The value of its resistance will become

A galvanometer of resistance 36 Omega is changed into an ammeter by using a shunt of 4 Omega . The fraction f of total current passing through the galvanometer is

A moving coil galvnometer is converted into an ammeter reading up to 0.03 A by connecting a shunt of resistance r/4 . What is the maximum current which can be sent through this galvanometer if no shunt is used (here r=resistance of galvanometer)

A moving coil galvnometer is converted into an ammeter reading up to 0.03 A by connecting a shunt of resistance r/4 . What is the maximum current which can be sent through this galvanometer if no shunt is used (here r=resistance of galvanometer)

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 -
