Is a capacitor a steady state circuit?

The circuit is at steady state when the voltage and the current reach their final values and stop changing. In steady state, the capacitor has a voltage across it, but no current flows through the circuit: the capacitor acts like an open circuit. How do you calculate steady state current in a capacitor? Is a capacitor fully charged in steady state?

Does a capacitor work differently at a phase 0?

@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.

What happens when a capacitor is charged in a steady-state condition?

Once the capacitor has been charged and is in a steady-state condition, it behaves like an open. This is opposite of the inductor. As we have seen, initially an inductor behaves like an open, but once steady-state is reached, it behaves like a short.

How do you find a steady state in a circuit?

Most circuits, left undisturbed for su ciently long, eventually settle into a steady state. In a circuit that is in steady state, dv = 0 and di = 0 for all voltages and currents in the circuit|including those of capacitors and inductors. dt dt Thus, at steady state, in a capacitor, i = C dv dt = 0, and in an inductor, v = Ldi = 0.

Why does a capacitor have a transient state?

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.

What does a capacitor look like in a inductor?

Thus, at steady state, in a capacitor, i = C dv dt = 0, and in an inductor, v = Ldi = 0. That is, in steady dt state, capacitors look like open circuits, and inductors look like short circuits, regardless of their capacitance or inductance. (This might seem trivial now, but we'll use this fact repeatedly in more complex situations later.)
