In the context of electrical systems (or any dynamic system), the steady state refers to the condition where all variables (like current, voltage, temperature, etc.) have stabilized and are no longer changing with time.
After an initial disturbance or change (like turning on a circuit or applying a voltage), the system may fluctuate or vary. But eventually, it reaches a point where these changes stop, and the system behaves predictably and consistently. This is the steady state.
For example, in an electrical circuit:
In simple terms, a "good" steady state is when the system is operating as expected, with no unwanted fluctuations, and all the variables have reached their final, stable values.

For example, in an electrical circuit:
- Steady state for a DC circuit would be when all the currents and voltages are constant, with no more transient fluctuations.
- In an AC circuit, steady state is when the current and voltage waveforms become sinusoidal and their amplitude and phase remain constant.
