a voltmeter shows 100v..wat is to be done to make it read 150v.
Answer Posted / 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
