Answer / madhusudhana
To increase Ammeter range, we add shunts and to increase voltmeter range, series resistance is connected to it. The device is calibrated accordingly.

Answer / tinku
if you want to make the deflection of voltmeter on 150 volt
on appling 100 V you can reduce the series resistance of
voltmeter it will cause more current to folw through it and
will show more (false) reading. But if you actually want to
increase its range to 150 volt i.e. it can measure upto 150
V you have to increase the series resistance

Answer / manoj sharma
Ther are following solutions.
1. increase the souce voltage up to 150V, which is being
measured by voltmeter.
2. volt meter measure the voltage by a niddle which is
clibrated to show difflection acording to magnetic force
develored in the potential coil. So increase the number of
turns up to 1.5 times of present no. of turns.
3. Replace the potential coil with new coil having
inductance 1.5 times of present potential coil.
Any way but why you want to do so.....plz tell me geetha...
