An ammeter whose resistance is 180`Omega` shows full scale deflection when the current is 2 mA. The shunt required to convert into an ammeter reading 20mA is (in ohm )

An ammeter whose resistance is 180 Omega gives full scale deflection when current is 2mA. The shunt required to convert it into an ammeter reading 20 mA (in ohms) is

A galvanometer having a resistance of 75 Omega gives the full scale deflection for the current of 25mA. The shunt required to convert it into an ammeter to measure the current up to 59 A is

A galvanometer has a resistance of 118Omega and gives full scale deflection for a current of 50 m A. if it is required to convert into an ammeter of range 3A, the shunt resistance should be

A galvanometer of resistance 15 Omega gives full scale deflection for a current of 2mA. Calculate the shunt resistance needed to convert it into an ammeter of range 0 to 5A.

A moving coil galvanometer of resistance 20 Omega gives a full scale deflection when a current of 1mA is passed through it. It is to be converted into an ammeter reading 20 A on full scale. But the shunt of 0.005 Omega only is available. What resistance should be connected in series with the galvanometer coil?

A moving coil galvanometer of resistance 20 Omega gives a full scale deflection when a current of 1mA is passed through it. It is to be converted into an ammeter reading 20 A on full scale. But the shunt of 0.005 Omega only is available. What resistance should be connected in series with the galvanometer coil?
