The **steady-state** process refers to a condition in a system where all the variables remain constant over time. In other words, it is the state where the system has stabilized, and no further changes are occurring.
Here’s a simple breakdown:
1. **Initial Phase**: When you first apply an input (like turning on a switch, applying voltage, etc.), the system begins to react and change its conditions (like current, voltage, temperature, etc.).
2. **Transients**: Initially, the system experiences changes that are not constant. This is called the *transient state*. The system’s variables (current, voltage, temperature, etc.) will be fluctuating and gradually adjusting to their final values.
3. **Steady-State**: After the system has had enough time to settle, it enters the **steady state**. In this phase, the variables stop changing, and the system reaches equilibrium. For example, in an electrical circuit, the voltage and current will remain constant once all transients die out.
### In Electrical Engineering:
For a simple example, consider an RLC circuit (Resistor, Inductor, and Capacitor). When you apply a voltage, the system doesn't immediately settle into a steady state. It will go through a transient phase where current and voltage change over time. But after a while, the system reaches steady state, where the current becomes constant (if DC) or oscillates in a predictable way (if AC).
### In Summary:
- **Steady-state** means the system is no longer changing with time.
- It occurs after the system has stabilized following any initial disturbances or changes.
- For electrical systems, it means current and voltage remain constant or oscillate at a fixed value (in AC systems).
