Question

What are initial, steady and transient conditions in network analysis?

Answer 1

Initial conditions are usually DC quanities as the curren throgh an inductor or the voltage across a capacitor. Steady State, SS, is the final condition ot a circuit as to DC and signal variations. Transient condition is what occurs in the circuit between these extremes. Generally the Laplace transform of a circuit is used in the analysis and circuit analysis breaks into two forms the transient and SS.

Answer 2

You start with a circuit which can have either AC or DC.
At a point in time you change something in the circuit.
The values of the voltages and the currents in the circuit at that instant of time are the initial conditions.

You then move into a regime where the amplitudes and the phases of the currents and voltages are changing.
This is the transient stage.

Eventually the amplitudes and phases of the currents become constant and this is called the steady state.

So you change something in the circuit and the circuit then takes time to settle down.
