Question
The damping ratio of a series circuit can be expressed as
Correct answer
(C) (R)/(2) √((C)/(L))
Solution
For a series circuit, the characteristic equation is given by:Comparing this with the standard second-order characteristic equation , we have:
1.
2.
Substituting into the second equation:Thus, the damping ratio is .Continue learning with Success Tracker
