Given information

It is given that :

Current    

Shunt resistance    

Galvanometer Resistance    

Full scale reading of the voltmeter =    

Step-by-step explanation

Step 1.

The resistance in ammeter must be very small such that there is no potential difference across it. In order to achieve it we connect shunt resistor in parallel with the 

galvanometer

Hence, equivalent resistance of ammeter is,
