Read the RLC-transient class notes.


For the circuit shown,

  • R = 4.7 kΩ
  • L = 470 mH
  • C = 100 nF

In the RLC circuit, the source has been at an initial voltage value of Vi = 6 V for a long time.
At t = 0, the source voltage abruptly jumps to Vf = 15 V.

Will the response of system be over-damped or under-damped?

If it is over-damped, what are the time constants corresponding to the two exponential decays?

Or if it is under-damped, what are the time constant of the decay and the damped oscillation frequency of the ringing response?
