A galvanometer can be flitrarted into a voltmeter by connecting:
Correct answer: A. High resistance in series
- A. High resistance in series
- B. Low resistance in parallel
- C. High resistance in parallel
- D. None of these
Explanation
To convert a galvanometer into a voltmeter, a high resistance, known as a multiplier resistor, is connected in series with the galvanometer. The purpose of the multiplier resistor is to limit the current flowing through the galvanometer when it is connected across a voltage source. By increasing the total resistance in the circuit, the multiplier resistor allows the galvanometer to measure the voltage drop across it accurately. The scale of the galvanometer can be calibrated to indicate the voltage directly.

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.
