An RLC series circuit is underdamped. To make it overdamped, the value of R

 [A]. has to be increased [B]. has to be decreased [C]. has to be increased to infinity [D]. has to be reduced to zero

Explanation:

For overdamping R is more.

 Chandru said: (Jun 11, 2014) What is mean by over&underdamped circuits ?

 Samata said: (Sep 22, 2014) Circuit which allows oscillation they are called as underdamped circuit and which won't they are overdamped.

 Shantha said: (May 29, 2015) What about LC?

 Tarun G said: (Jul 11, 2015) LC is undamped because the value of resistance is zero. And for any circuit when R=0; damping coefficient (for series RLC=R/2L) is also zero.

 Nitesh Jain said: (Aug 26, 2015) Damping ratio (zeta) = R/2(C/L)^1/2.

 Divesh Jain said: (Sep 27, 2015) What is mean of damping ratio?

 Divesh Jain said: (Sep 29, 2015) What is the mean of damping ratio can anyone explain this?

 Sandeep Kumar said: (Jul 3, 2016) It is a measurement that measures how oscillations decay in a system after a disturbance.

 Sonia Gandhi said: (Feb 7, 2017) No. It is not possible. It has to be decreased.

 Ramana said: (Jun 8, 2017) What is the difference between underdamped, overdamped, critical damped?

 Manimala said: (Aug 26, 2017) During this, over damped condition L and C are more or less?

 Shubham Panwar said: (Oct 7, 2017) Underdamped in this damping ratio is between 0 and 1. Over damped damping ratio is greater than 1. Critically damped damping ratio is 1.

 Aishu.M said: (Jan 27, 2018) Can anyone say the formula for damping ratio?

 Swetha said: (Feb 7, 2018) Please give the formula for damping ratio.

 K.Panda said: (Mar 8, 2018) 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.

 Pravallika said: (Aug 26, 2018) It may be like this; (R/2)^2L/C.
