An inductor looks like a piece of wire to DC. It will thus look like a resistor, and inductor properties do not apply.

What is inductor functioning?

Actually Inductor oppose the change of current in the circuit..... Acts like a short circuit in steady state condition....


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 are transient and steady state conditions in Markov Chains?

Please consult some book.


Can you connect an AC source in series to DC source - then what happens to the current under a steady state condition?

With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.

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.

How long has the universe existed going by the Steady State Theory?

The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't). According to the Steady-State Theory, the Universe has no beginning and no end.
