Given battery is 4.5 volts.
that means it can produce potential difference from Zero to 4.5 V.
So voltmeter of range 0-4.5 volts can be used.
Even voltmeter greater than 4.5 can be used.[error associated with every reading will be more]
If we use Voltmeter lesser than 4.5 range, than deflection in meter will be full that is greater than its maximum limit.
