The current passing through the coil of galvanometers is directly proportional to:
Correct answer: A. Angle of deflection
- A. Angle of deflection
- B. Magnetic field
- C. Number of turns
- D. Resistance of the coil
Explanation
In a galvanometer, the current passing through the coil is not directly proportional to the angle of deflection. The angle of deflection is a measure of the current flowing through the coil, but it's not the determining factor. Instead, the current is directly proportional to the torque acting on the coil, which is produced by the magnetic field generated by the current flowing through the coil.

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.
