Steady-state

A condition or state of equilibrium within a system or process. It signifies a balance where the input equals the output, and the key properties or variables remain constant over time or oscillate within a narrow range. It implies a lack of significant change, suggesting stability, and is often used in the context of physical, chemical, biological, or economic systems. The 'steady' aspect refers to consistent behavior, and 'state' alludes to a particular condition of the subject.

Steady-state meaning with examples

• In a chemical reaction, a steady-state might be achieved when the rate of reactant consumption equals the rate of product formation, and the concentrations of reactants and products remain relatively unchanged. This equilibrium allows for continuous operation. This contrasts with dynamic systems where concentrations are constantly fluctuating.
• An economic system might reach a steady-state when economic growth is sustained at a constant rate, and inflation remains stable. This indicates a balanced economic performance where the system is neither booming nor in recession. Policy makers often attempt to maintain this.
• Physiologically, a steady-state can describe a state of homeostasis. The body's internal environment, such as temperature and blood sugar levels, are maintained within an acceptable range through a constant equilibrium of various processes, such as sweating.
• In electrical engineering, a steady-state often describes the stable condition of a circuit after the initial transient effects have subsided, such as during a specific input. The voltage and current levels remain consistent for a specified input. These systems are highly sought for stability.
