Which condition is suitable for indicating instruments in order to get the best results? Correct Answer Damped slightly less than the critical value

Explanation:

Indicating instruments are the electrical instruments that indicate the instantaneous value of an electrical quantity being measured such as current, voltage, resistance and power. Their indicators are given by pointers which move over calibrated dials. Examples – Ammeter, Voltmeter, etc.

Case 1:

Under damped: If the instrument is under-damped, the pointer will oscillate about the final position for some time before coming to rest.

Case 2:

Overdamped:  if the instrument is overdamped, the pointer will become slow and lethargic.

Case 3:

Critically damped:  if the instrument is critically damped, the pointer comes will come to the correct reading quickly without oscillating about it.

Therefore to get the best result for indicating instruments, it should be damped slightly less than the critical value.
