A galvanometer acting as a voltmeter should have
Options
- Alow resistance in series with its coil
- Blow resistance in parallel with its coil
- Chigh resistance in series with its coil
- Dhigh resistance in parallel with its coil
Correct answer
C. high resistance in series with its coil
Step-by-step solution
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 is draws negligible current from the circuit.
