Does the circuit being in steady state mean that there is no energy storage
Suppose we start building up a current from zero into an inductor. With no current in it, there is no magnetic field and therefore zero energy, but as the current rises, the magnetic field grows, and the energy stored grows with it. We actually have a way of determining the rate at which the energy stored is growing from what we know already ... - Download [PDF]

15.7: Forced Oscillations
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of the oscillator is known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic. After some time, the steady state solution to this differential equation is

How does current flow in a circuit with a capacitor?
The presence of a parallel-plate capacitor means that in part of the circuit (only a small part; capacitors rarely have a gap as large as one millimeter) there is no movement of electrons, only a buildup of field (accompanied by electrons if the capacitor is not a vacuum type).
Steady State vs. Transient State in System Design and Stability ...
Moreover, when a system is experiencing a steady state, the system is considered to be stable. Overall, determining the steady state is critical, since many electronic design specifications are presented in terms of a system''s steady state characteristics. Furthermore, steady-state analysis is an invaluable component in the design process.

What does it mean when a capacitor is in steady state?
What happens in steady state in circuit? In electronics, steady state is an equilibrium condition of a circuit or network that occurs as the effects of transients are no longer important. Steady state is reached (attained) after transient (initial, oscillating or turbulent) state has subsided. During steady state, a system is in relative stability.
DOE Explains...Batteries | Department of Energy
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.

The voltage across the inductor therefore drops to about 37 % 37 % of its initial value after one time constant. The shorter the time constant τ L, τ L, the more rapidly the voltage decreases.. After enough time has elapsed so that the current has essentially reached its final value, the positions of the switches in Figure 14.12(a) are reversed, giving us the circuit in part (c).

Energy Stored on a Capacitor
The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor.The voltage V is proportional to the amount of charge which is already on the capacitor.

It is worth noting that both capacitors and inductors store energy, in their electric and magnetic fields, respectively.

Why is there current if there isn''t any potential difference?
Water in a river can pass through a horizontal section of the river where there is no change in height (potential difference) where it is being pushed by the water from upstream that does have a change in height.
