engineering recuitment GATE EE 2023-24 Test Series Electrical and Electronics Measurements Indicating Instruments
Consider the following statements
1. In general, all the indicating instruments are 2nd order instruments with a damping ratio(ζ) lies between 0.6 and 0.8.
2. For over damping no oscillations are present but the pointer moves very slowly to the final reading
3. For critical damping the pointer reaches final value in quickest possible time without any oscillations called 'dead beat'.
4. The time taken by the pointer depend only on 'controlling torque'
