The gravity controlled instrument has crowded scale because current is proportional to________________?
Correct answer: C. sine of deflection angle
- A. balancing weight
- B. deflection angle
- C. sine of deflection angle
Explanation
In a gravity-controlled instrument, controlling torque is proportional to sin θ. Since the deflecting torque balances it, the current is also proportional to sin θ, producing a crowded scale.
