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 …

However, as the capacitor voltage stabilizes (reaches steady state), the current through the capacitor drops to zero. At steady state, the capacitor essentially acts as an open circuit for DC current, although it can still pass alternating current (AC) depending on its frequency and the circuit configuration.
