Energy Stored in Inductor Suppose that an inductor of inductance is connected to a variable DC voltage supply. The supply is adjusted so as to increase the current flowing through the inductor from zero to some final value 𝐼. As the current through the inductor is ramped up, a voltage 𝑣 = 𝑙 appears across the inductor, which acts to oppose the increase in the current. Clearly, work ...
When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up to its steady-state value.
Doesn't it take an infinite time for the inductor to reach its steady state (where it behaves as a connecting wire). So, wouldn't the rod move in the direction of its initial velocity forever? What will happen once a steady current is achieved in the circuit?
What happens to energy stored in inductor when it is discharged after it reaches steady state An ideal inductor (zero resistance) that is discharged by a zero resistance path (a short circuit) will maintain the energy in the inductor until the end of time.
Instead, the energy is stored in the magnetic field as the rising current forces the magnetic lines of force to expand against their tendency to become as short as possible—somewhat as a rubber band stores energy when it is stretched. Figure 1 Determining the energy stored by an inductor
Figure 1 Determining the energy stored by an inductor In resistance circuits where the current and voltage do not change with a change in time, the energy transferred from the source to the resistance is W = Pt = VIt. Although the voltage remains constant in the circuit of Figure 1 (a), the current steadily increases as time elapses.
As the current through the inductor is ramped up, a voltage = appears across the inductor, which acts to oppose the increase in the current. Clearly, work must be done against this voltage by the voltage supply in order to establish the current in the inductor.

Find the current through the $mathrm{5 space mH}$ inductor when the circuit reaches a steady state. When the circuit reaches a steady state, a current of $mathrm{4 space A}$ will flow through the resistor (since voltage across the inductors are zero). The inductors themselves are ideal, and have a resistance of $mathrm{0 space Omega}$.
There is no steady state. If the rod was not allowed to move, then the inductor would simply keep the current going until consumed by the tiny resistance in the wires. …

At the steady state condition, inductor is acting as short circuit therefore current i(t) can be replaced by current $I_m$. Example 1: Find the energy stored by the inductor in the circuit of Fig. 2 when the current through it has reached its final value.
After 2 half-lives, you will have reached 75% of steady state, and after 3 half-lives you will have reached 87.5% of steady state. How does an inductor behave in steady-state? When a steady state DC current will flow through the inductor, the inductor will acts as a short circuit equal to a piece of wire .
In addition, we can use the inductor''s energy storage and return capability to great advantage in our electronic circuits. Boost Converters, which are used to increase a DC voltage, say from a 9V battery at the input to the 100V or more needed to drive a vacuum fluorescent display, use an inductor''s ability to store and return energy to "boost" the voltage. …

When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up to its steady-state value.
Inductors and capacitors reach a steady state when they have been charged or discharged to their maximum capacity, and the current flowing through them has reached a constant value. This can happen in different ways depending on the circuit and the input signal. Why is the steady state important in circuits?
What happens to the energy stored in an inductor when it is discharged after it reaches steady state? In transient state analysis, the voltage in the inductor changes its polarity when discharged and opposes change in current.
There is no steady state. If the rod was not allowed to move, then the inductor would simply keep the current going until consumed by the tiny resistance in the wires. However, there is still current going through the rod, so there is a force pushing it left, so it instead reverses direction and starts oscillating.

When a circuit is first energized, the current through the inductor will still be zero, which is characteristic of opens. Once at steady-state, the current has leveled out and therefore the voltage across the inductor will approach zero, which is characteristic of shorts.
In a circuit that is in steady state, dv dt = 0 and di dt = 0 for all voltages and currents in the circuit|including those of capacitors and inductors. Thus, at steady state, in a capacitor, i = Cdv dt = 0, and in an inductor, v = Ldi dt = 0. That is, in steady state, capacitors look like open circuits, and inductors look like short circuits ...
