The SI unit of galvanometer constant is C/BAN
Correct answer: D. None of these
- A. amp/radian
- B. N-m/sec²
- C. N-amp/radian
- D. None of these
Explanation
Option D is the correct answer because none of the other options accurately represent the SI unit of the galvanometer constant, which is degrees per ampere (deg/A). This unit directly reflects the relationship between the deflection angle in degrees and the current in amperes flowing through the galvanometer.

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.
