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 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 coild 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 20A. But the resistance of the only shunt available is 0.005Omega . What resistance should be connected in series with the galvanometer coil?

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

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

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 with a resistance of 12 Omega gives full scale deflection when a current of 3 mA is passed. It is required to convert it into a voltmeter which can read up to 18 V . the resistance to be connected is

A galvonometer of resistance 20 Omega gives a full scale deflection with a current of 0.04A is passed through it. It is derised to convert it into an ammeter of range 20A . The only shunt available is 0.05 Omega . The resistance that must be converted in series with the coil of the galvonometer is

A galvanometer of resistance 100Omega gives full deffection for a current 10^(-5) the value of shunt required to convert it into ammeter of range 1 ampere is:-

A moving coil galvanometer has a resistance of 200 Omega and gives a full-scale deflection with a current of 10mA. Explain how you would convert it into (i) an ammeter reading up to 1A, (ii) voltmeter reading up to 10 V. Also calculate the resistance of an ammeter and voltmeter so formed.
