A proper combination of a galvanometer and a series resistance acts as:
Correct answer: A. Voltmeter
- A. Voltmeter
- B. Ammeter
- C. Ohmmeter
- D. None of these
Explanation
When a high resistance is connected in series with a galvanometer, it forms a voltmeter. The series resistance is chosen such that the total resistance of the combination is much higher than the internal resistance of the galvanometer. This allows the voltmeter to measure potential differences across various components in a circuit without drawing significant current from the circuit. The voltmeter is connected in parallel with the component being measured.

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.
