A microammeter has a resistance of 
and full scale range of 
. It can be used as a voltmeter or as a higher range ammeter provided a resistance is added to it. Pick the correct range and resistance combination
A
50 V range with 
resistance in series
resistance in series
B
10 V range with 
resistance in series
resistance in series
C
10 mA range with 
resistance in parallel
resistance in parallel
D
10 mA range with 
resistance in parallel
resistance in parallel
Text Solution
Verified by ExpertsThe correct answer is:
B
To convert a galvanometer into an ammeter, a shunt 
is connected in parallel with it. To convert a galvanometer into a voltmeter, a resistance 
is connected in series with it.
