An RLC series circuit is underdamped. To make it overdamped, the value of R
has to be increased
has to be decreased
has to be increased to infinity
has to be reduced to zero
Answer: Option

For series Q = 1/R √L/C.

And, DAMPING RATIO IS REVERSE OF 2Q from there you can see that to decrease the damping ratio you have to increase and decrease respectively.

Thank you everyone for explaining.

It may be like this;

(R/2)^2<L/C.
(R/2)^2=L/C.
(R/2)^2>L/C.

Underdamped-------------- (R/2L)^2 < 1/LC.
critical damped------------- (R/2L)^2 = 1/LC.
overdamped--------------- (R/2L)^2 > 1/LC.

To make underdamped to overdamped for RLC series circuit the value of R should be increased.

Please give the formula for damping ratio.

Can anyone say the formula for damping ratio?

Underdamped in this damping ratio is between 0 and 1. Over damped damping ratio is greater than 1. Critically damped damping ratio is 1.

During this, over damped condition L and C are more or less?

Ramana said:   8 years ago
What is the difference between underdamped, overdamped, critical damped?

No. It is not possible. It has to be decreased.
