What are the behaviors of capacitors and inductors at time t=0?
Inductance and capacitance are effects that limit rate of change. Once things have settled out, there is no more change, and they have no further effect. So in the long-term, steady-state, capacitors and inductors look like what they are; they act like you''d expect them to act if you knew how they were constructed, but didn''t know capacitance or inductance even existed.
