An ammeter is to be constructed which can read currents up to 2.0A. If the coil has a resistance of `25(Omega)`and takes 1mA for full-scale deflection, what should be the resistance of the shunt used?

A volmeter coil has resistance 50.0 Omega and a resistor of 1.15 k Omega is connected in series. It can read potential differences upto 12 V. If this same coil is used to construct an ammeter which can measure currents up to 2.0 A, what should be the resistance of the shunt used?

(a) Briefly explain how a galvanometer is converted into an ammeter. (b) A galvanometer coil has a resistance of 15 Omega and it shows full scale deflection for a current of 4 mA. Convert it into an ammeter of range 0 to 6 A.

A moving coil galvanometer has a resistance of 50 Omega and gives full scale deflection for 10 mA . How could it be converted into an ammeter with a full scale deflection for 1 A

The ratio of the shunt resistance and the resistance of a galvanometer is 1:499 . If the full scale deflection current of the galvanometer is 2mA , the range of the ammeter is
