A galvanometer has a resistance of `16Omega`. It shows full scale deflection when a current of 20mA is passed through it. The only shunt resistance available is 0.06W which is not appropriate to convert galvanometer into ammeters. How much resistance should be connected in series with the coil of galvanometer so that the range of ammeter is 8A?

A galvanometer has a resistance of 16 Omega and gives a full scale deflection, when a current of 20 mA is passed through it. The only shunt resistance available is 0.04 Omega which is not appropriate to convert galvanometer into an ammeter. How much resistance should be connected in series with coil of galvanometer so that the range of ammeter is 10 A?

A Galvanometer has a resistance of 25 Omega and its full scale deflection current is 25 muA . What resistance should be added to it to have a range of 0 -10 V.

A moving coil galvanometer of resistance 40 Omega gives full scales deflection when a current of 0.25 mA is paased through it. To convert it to voltmeter of range 10 V, the resistance requried to be placed in series is
