Question:
In a Galvanometer, if the number of turns in the coil are doubled, then the electrical current sensitivity will be:
In a Galvanometer, if the number of turns in the coil are doubled, then the electrical current sensitivity will be:
Show Hint
Remember that the sensitivity of a Galvanometer is directly proportional to the number of turns in the coil. Doubling the number of turns doubles the sensitivity.

- Sensitivity is independent of number of turns in coil
- Doubled
- Four times the initial value

The Correct Option is C
Solution and Explanation
The sensitivity \( S \) of a Galvanometer is directly proportional to the number of turns \( N \) in the coil. The formula for sensitivity can be written as:
\[
S \propto N
\]
If the number of turns in the coil is doubled, the sensitivity will also double. Thus, the new sensitivity will be double the initial value.
Therefore, the sensitivity will be doubled.
