Answer :

Concepts/Formula used:


Ohm’s Law:


Potential Difference (V) across a resistor of resistance R when current I passes through it is given by Ohm’s law:



Note that 1A = 100mA.


Note that the current at full deflection is .


The voltmeter can be represented as follows:



It is given that the resistances are in series.





Potential difference is maximum when there is full scale deflection and is given by Ohm’s law:





Thus, maximum potential difference that can be measured is 6V.
