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.

What happens to capacitor in open circuit?

Once the capacitor has reached the full voltage of the source, it will stop drawing current from it, and behave essentially as an open-circuit. ... For all practical purposes, though, we can say that the capacitor voltage will eventually reach 15 volts and that the current will eventually equal zero.

What is meant by open capacitor?

For a good capacitor, the resistance will be low in the beginning and will gradually increase. If the resistance is low at all times, the capacitor is a Shorted Capacitor and we have to replace it. If there is no movement of the needle or the resistance always shows a higher value, the capacitor is an Open Capacitor.
