Overdamping will make instruments:

Concept:

Classification of instruments on the basis of damping:

1.) Overdamping:

• The value of the damping ratio is greater than 1.
• In case of overdamping, the instrument will become slow and lethargic and rise very slowly from its zero position to a steady state position.

​2.) Undamped:

• The value of the damping ratio is equal to 0.
• In this case, the instrument never settles down and always oscillates about its mean position.

3.) Under-damped:

• The value of the damping ratio lies between 0 to 1.
• In this case, the system initially oscillates about its mean position but settles down to a steady state.

4.) Critical-damping:

• The value of the damping ratio is equal to 1.
• This damping returns the system to equilibrium as fast as possible without any oscillations.
