A galvanometer with a coil of resistance 40 ohm gives a full scale deflection for a current of 5 mA. How will you convert it into an ammeter of range 0-5 A ?

A moving coil galvanometer has a resistance of 25Omega and goes a full scale deflection for a current of 10mA. How will you convert it into voltmeter having a range of 0.100V?

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

Calculate the value of resistance needed to convert a moving coil galvanometer of 60 Omega into an ammeter of range 5 A which gives full scale deflection for a current of 50 mA and into voltmeter of range 0-50 V.

A galvanometer of resistance 5 ohms gives a full scale deflection for a potential difference of 10 mV. To convert the galvanometer into a voltmeter giving a full scale deflection for a potential difference of 1 V, the size of the resistance that must be attached to the voltmeter is

A milliammeter of resistance 5 ohm gives a full scale deflection for a current of 15 mA. If the mulliammeter is to be used to measure current upto 1.5 A, then the resistance that must be attached to the milliammeter is

A galvanometer whose resistance is 120 Omega gives full scale deflection with a curretn of 0.5 A so that it can read a maximum current of 10 A . A shunt resistance is added in parallel with it. The resistance of the ammeter so formed is

A galvanometer of resistance 99 Omega requires 5 mA current for full scale deflection. It can be converted into an ammeter of range 0.5 A by connecting a shunt resistance of

A moving coil galvanometer of resistance G gives full scale deflection for a certain current. The shunt resistance required to convert it to measure a current n times the initial current is

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?
