A galvanometer acting as a voltmeter should have |
|||
|
a) |
Low resistance in series with its coil |
b) |
Low resistance in parallel with its coil |
|
c) |
High resistance in series in series with its coil |
d) |
High resistance in parallel with its coil |

(c) Voltmeter has high resistance and is always connected in parallel with the circuit. So, to convert a galvanometer into voltmeter, a high resistance must be connected in series with it so that it draws negligible current from the circuit. |
