The sensitivity of a moving galvanometer is given by
Correct answer: A. Zero
- A. Zero
- B. \( \frac{cAN}{B} \)
- C. \( \frac{C}{BAN} \)
- D. \( \frac{ABC}{C} \)
Explanation
The sensitivity (\(S\)) of a moving coil galvanometer is determined by the formula:\[ S = \frac{BAN}{C} \]Where:- \(B\) = magnetic field strength- \(A\) = area of the coil- \(N\) = number of turns in the coil- \(C\) = control torque or couple per unit twist.This option aligns with the correct formula for the sensitivity of a moving coil galvanometer.### Correct Answer:(a) \( \frac{BAN}{C} \)

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.
