A galvanometer of coil resistance 50 Ω deflects full scale for a current of 3.50mA. What series resistance should be used with this galvanometer to construct a voltmeter which deflects full scale for 35.0 V ?
r=50 Ω I=3.50mA=0.0035 V=35.0v R=?
I= V/R
I honestly don't know- There is very little explanation in the unit -Help me get started please?
