To convert a galvanometer into a voltmeter, we connect with it a:
Correct answer: B. A high value series resistance
- A. Shunt resistance
- B. A high value series resistance
- C. Parallel resistance
- D. None of these
Explanation
To convert a galvanometer into a voltmeter, a high-value resistor is connected in series with the galvanometer. The purpose of this series resistor is to limit the current passing through the galvanometer when it is connected across a voltage source. By choosing an appropriate high resistance value, the voltmeter can measure voltage across the device without drawing excessive current, thereby ensuring accurate voltage measurement.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
