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...
