7.4 The Step-Response
of a RC Circuit (2)
•Integrating both sides and considering the initial conditions, the solution of the equation is:
Final value at t -> ∞
Initial value at t = 0
Source-free Response
Complete Response =       Natural response      +       Forced Response
                     (stored energy)                     (independent source)
                                            =                  V0e–t/τ           +             Vs(1–e–t/τ)
