What is inductor functioning?
Actually Inductor oppose the change of current in the circuit..... Acts like a short circuit in steady state condition....
What is the behaviour of inductor for dc supply?
When a DC supply is applied to an inductor, it initially resists changes in current due to its property of self-inductance. As the current starts to flow, the inductor gradually stores energy in its magnetic field. Once the current reaches a steady state, the inductor behaves like a short circuit, allowing the current to flow freely without any opposition. Thus, in the long term, the inductor does not impede DC, allowing it to pass through.
What happen when inductor has fully charged?
When an inductor is fully charged, it reaches a steady state where the current flowing through it is constant. At this point, the inductor behaves like a short circuit, and the voltage across it drops to zero, as it has stored maximum energy in the magnetic field. If the circuit is interrupted or switched off, the inductor will attempt to maintain the current flow, causing a voltage spike that can potentially damage components unless managed properly.
Why does a switch spark when disconnecting a coil carrying high dc current?
An inductor resists a change in current. If you have a steady state current going through an inductor and you attempt to suddenly increase the current, the inductor will nearly instantaneously present a higher resistance so that the current does not immediately change. Its resistance, then, will start to decrease as the current ramps up to the new value. Similarly, if you have a steady state current going through an inductor and you attempt to suddenly decrease the current, the inductor will nearly instantaneously present a lower resistance so that the current does not immediately change. Its resistance, then, will start to increase as the current ramps down to the new value. That's all just background information so you can understand what an inductor is. If you have a steady state current going through an inductor and you attempt to suddenly decrease the current to zero by opening the circuit, the inductor will respond by attempting to maintain the current, but that current has nowhere to go. This creates a large negative voltage spike across the inductor. Think about it. Ohm's law says that voltage is current times resistance. You have some current; you have infinite resistance; therefore you must have infinite voltage. In fact, a theoretical pure inductor will do exactly that - generate an infinitely large negative voltage spike. That does not happen in practice, but it is very common to see transients of several hundred or thousand volts. This is why you need to have some kind of suppression circuit in place - otherwise that transient will go back and blow out whatever circuit is driving it.
What happens to the speed of motor while the excitation current is decreasing?
Assuming there is no mechanical load, as the speed approaches the synchronous speed the slip decreases and the current induced in the rotor also decreases. The stator coil begins to approximate a pure inductor and that causes the current to fall. In the steady state the power drawn is used to overcome friction in the bearings and windage only.
What happens to the voltage over the inductor in the steady state as a result of Faraday's law?
In the steady state, the voltage over the inductor increases as a result of Faraday's law.
What happens when a population reaches a steady state?
It then declines
What happens when a capacitor reaches a steady state?
when a capacitor reaches it, it acts as a battery
What do you mean by steady state reactance?
If you use AC components (i.e. inductor or capacitor ) on DC circuit, they will initially behave different than at steady state. Steady state is the state in which the behavior is not changing with time. (theoretically after infinite time, practically within small time any ckt reaches steady state)
What component limits current in a circuit?
A resistor or an inductor. The inductor limits transient current, not steady state current.

What is steady state error in control system?
Steady state error in control systems is the difference between the desired output of a system and the actual output when the system reaches a constant state under a specific input. It indicates how well the system is tracking the desired setpoint. Lower steady state error values indicate better performance of the control system.
What are the differences between steady state and rapid equilibrium in a system?
In a system, steady state refers to a condition where the system's variables remain constant over time, while rapid equilibrium occurs when the system quickly reaches a balance between different components. Steady state involves a stable state of the system, while rapid equilibrium involves a quick adjustment to reach a balanced state.
What are the characteristics of a system that is overdamped?
An overdamped system is characterized by slow response time and no oscillations in its output. It reaches its steady state without any overshoot or oscillations.
