Voltage sensitivity of a moving coil galvanometer doesn't depend on :
- A Magnetic field
- B Number of turns of the coil
- C Resistance of the coil
- D torsional constant of the spring
Answer & Solution
Correct Answer
(C) Resistance of the coil
Step-by-step Solution
Detailed explanation
The voltage sensitivity \(\left( S _{ v }\right)\) of a moving coil galvanometer is defined as the deflection per unit voltage applied across its terminals. It is given by the formula: \(S_V=\frac{\theta}{V}=\frac{N A B}{k R}\)
