Sensitivity of galvanometer is defined as
Correct answer: A. The deflection produced per unit microampere current
- A. The deflection produced per unit microampere current
- B. The deflection per force
- C. Force per unit area
- D. None of them
Explanation
The correct answer is Option A: The sensitivity of a galvanometer is defined as the deflection produced per unit microampere of current. This indicates how responsive the galvanometer is to small currents, which is crucial for accurate measurements. Option B is incorrect because it incorrectly associates sensitivity with force, not current. Option C describes pressure, not relevant to galvanometer sensitivity. Option D is incorrect as Option A provides the correct definition.

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.
