A n ammeter of resistance `100 Omega` can measure a maximum current of 5 mA. What will you do to measurea maximum current of 5 A .

Resistance of a galvanometer is 25 ohm it can carry a current of 0.5 mA. How can it be used to measure a current of 0.5 A.

How can a voltmeter of resistance 200 ohm and measuring 10 V be used to measure a current of 5 A?

A galvanometer of resistance 80 ohm gives full scale deflection for a current of 4 mA. How will you convert it into a voltmeter of range 0.5 V?

A moving coil galvanometer of resistance 100Omega is used as an ammeter using a resistance 0.1 Omega . The maximum diflection current in the galvanometer is 100 muA . Find the minimum current in the circuit so that the ammeter shows maximum deflection

You are given several identical resistors each of value 10Omega and each capable of carrying a maximum current of 1 A. It is required to make a suitable combination of these to resistances to produce a resistance of 5Omega which can carry a current of 4 A. The minimum number of resistors required for this job is

A galvanometer with a coil of resistance 12.0 ohm shows full scale deflectio for a current of 2.5 mA. How will you convert the meter int an ammeter of range 0 to 7.5 A
