Question

What is steady state concept?

Answer 1

The steady state concept refers to a condition in a system where all variables (like voltage, current, temperature, etc.) remain constant over time. In electrical and electronics systems, the steady state typically occurs after any initial transients (temporary changes) have settled down, and the system reaches a stable operating point.

For example:

1. In an electrical circuit with a DC voltage source, the steady state is when the current and voltages in the circuit stop changing and become constant after any initial fluctuations caused by switching on the circuit.
   

1. In AC circuits, the steady state occurs when the system has adjusted to the AC waveform, and the currents and voltages are sinusoidal and at constant amplitude, with no further changes in shape or frequency.
   

In simpler terms, the steady state is the "final" condition of a system where everything becomes stable and no longer changes over time.
