Question:
The gravity controlled instrument has crowded scale because current is proportional to
The gravity controlled instrument has crowded scale because current is proportional to
Show Hint
In gravity-controlled instruments, the deflection is proportional to the sine of the deflection angle, which makes the scale crowded.

- gravitational force
- balancing weight
- deflection angle
- sine of deflection angle
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the principle.
In a gravity-controlled instrument, the deflection of the needle depends on the current. The deflection angle is proportional to the sine of the deflection angle, which causes the scale to be crowded.
Step 2: Conclusion.
Thus, the current is proportional to the sine of the deflection angle, corresponding to option (D).
