A galvanometer has a resistance of `100 Omega` and its full scale deflection current is `100 mu A`. What shunt resistance should be added so that the ammeter can have a range of 0 to 10 mA ?.

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 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 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 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 volt meter has a resistance of 100 Omega and measures 10 V . How can it be used to measure 50 V ?

A galvanometer has a resistance of 40 Omega and a current of 4 mA is needed for a full scale deflection.What is the resistance and how is it to be connected to convert the galvanometer into a voltmeter of 0.5 V range ?

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
