Initial conditions are completely specified only when both voltage and current for all capacitors and all inductors is known. Assume zero for the capacitor voltage and/or inductor current if no information is given. Every inductor has two initial conditions: current and voltage.
The transient state is there because the voltage source was started at phase zero. That's not where it would be in the steady state when the capacitor's instantaneous voltage was zero. Look at the phase shift between the voltage source and the capacitor voltage in the steady state.
DC has zero rate of change of voltage hence, a capacitor takes no current but, if you turned-up the DC voltage, the capacitor "resists" that change by taking a lot of current until the voltage ceases changing. Then the capacitor takes zero current again. The faster the change in voltage, the higher the current taken by the capacitor. No weirdness.
@MSKB It does not work any differently at any phase, it's just a capacitor. Your circuit just does not start from a steady state. Same as applying a DC step to a capacitor, it takes time for the circuit to settle to new DC conditions. The transient state is there because the voltage source was started at phase zero.
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
Therefore we can state a particularly important characteristic of capacitors: The voltage across a capacitor cannot change instantaneously. (6.1.2.7) (6.1.2.7) The voltage across a capacitor cannot change instantaneously. This observation will be key to understanding the operation of capacitors in DC circuits.
