A galvanometer acting as a voltmeter should have

A galvanometer acting as a voltmeter should have

Options

  1. Alow resistance in series with its coil
  2. Blow resistance in parallel with its coil
  3. Chigh resistance in series with its coil
  4. 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.
