Current Question (ID: 16847)

Question:
$\text{What is the relation between voltage sensitivity } (\sigma_v) \text{ and current sensitivity } (\sigma_i) \text{ of a moving coil galvanometer? (Resistance of Galvanometer } = G)$
Options:
  • 1. $\frac{\sigma_i}{G} = \sigma_v$
  • 2. $\frac{\sigma_v}{G} = \sigma_i$
  • 3. $\frac{G}{\sigma_v} = \sigma_i$
  • 4. $\frac{G}{\sigma_i} = \sigma_v$
Solution:
$\sigma_i = \frac{\theta}{i} = \frac{\theta}{iG} \cdot G = \sigma_v G \Rightarrow \frac{\sigma_i}{G} = \sigma_v$
