▶A 'damping' device prevents the oscillation of the moving system and enables the latter to reach its final position quickly.
♦Ex:- sound-proofing technology dampens the oscillations of sound waves.
❖ Damping devices can operate mechano -hydraulically as throttle valves or bypass valves or electro-mechanically.
❖ It is a mechanical device designed to dissipate kinetic energy.

A 150 moving iron voltmeter is intended for 50hz , has a resistance of 3 kohm. find the series resistance required to extent the range of instrument to 300v. if the 300v instrument is used to measure and dc voltage of 200v.
find the voltage across the meter.?
