A galvanometer acting as a voltmeter will have a coil with:
Correct answer: B. A high resistance in series
- A. A high resistance in parallel
- B. A high resistance in series
- C. A low resistance in parallel
- D. A low resistance in series
Explanation
The resistance of the coil of the galvanometer on its own is low; hence, to convert a galvanometer into a voltmeter, its resistance must be increased. For this, an appropriate high resistance is joined in series with the galvanometer.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
