Construction of a voltmeter to read required voltage and an ammeter to read required current, by converting a Galvanometer

Why a DC ammeter cannot read AC?

How can you convert a galvanometer into an voltmeter? Can you use Voltmeter to measure current in a circuit?

A galvanometer of resistance 100 Omega is converted to a voltmeter of range 10 V by connecting a resistance of 10k Omega . The resistance required to convert the same galvanometer to an ammeter of range 1 A is

A galvanometer can be converted into a voltmeter by connecting

To convert a galvanometer into an ammeter we connet which one of the following to the galvanometer ?

A galvanometer of resistance 50 ohm shows full scale deflection when 1.5 mA current flows. how can you convert it into (a). Voltmeter that reads 1 volt at full scale deflection (b) Ammeter that reads 30 mA at full scale deflection .

Shown an arrangement to measure the emf (epsilon) and internal resistance r of a battery. The voltmeter has a very high resistance and the ammeter also has some resistance.The voltmeter reads 1.52 V when the switch S is open.When the switch is closed the voltmeter reading drops to 1.45 V and the ammeter read 1.0A Find the emf and the internal resistance of the battery.
