A voltmeter has a resistance G and range V. Calculate the resistance to be used to extend its range to nV.
The we require n resistance so , total resistance is nG
To extend the range of a voltmeter we add a resistance of more value in series with the meter.value of added resistance(shunt) Rs=Rm+V'/ImHere V' is the new range, Rmis resistance of voltmeter and Imis maximum value of current through voltmeter that is Vm/Rmfor this case Rm=G Vm=V and V'=nVso Rs=G+nG=(1+n)GSher Mohammadfaculty askiitians
