Why inductor does not work in DC source?
It does work on d.c., but it really depends on what you want it to do!
Why a transformer designed for a 120V AC input will often burn out if connected to a 120V DC source?
All transformers are designed to work on AC. They do not work on DC.If you connect an inductor to DC, the current will increase until the capacity of the source or the conductance (1/resistance) capacity of the inductor and conductors is reached. Often, this condition will overheat and destroy the inductor, or destroy the source. A transformer is not an exception, as it is a form of inductor.
Why we use the inductor?
To answer these questions I will tell you which devices or equipments are inductive.These include:TransformersHair clipers,hair blowers,motorsYou hopefully know what those devices or equipments are used for,hence why we use inductors.
Is it possible to heat coil using dc power supply?
Yes, it possible to heat a coil using dc power supply. An inductor resists a change in current, proportional to voltage and inversely proportional to inductance. The equation of an inductor is di/dt = v/L An ideal inductor, if connected to an ideal DC supply, with ideal conductors, would ramp up current in a linear fashion without limit, eventually reaching infinity amperes after infinite time. Since no inductor is ideal, nor is any DC supply, nor is any conductor, the current would reach a maximum based on the capacity of the DC supply and the DC resistance of the inductor and conductors. Since the DC resistance of the inductor is also not zero, this means, by Ohm's law, that the inductor must dissipate some power. That will cause the inductor to heat up.
What happens when a inductor reaches a steady state?
An inductor looks like a piece of wire to DC. It will thus look like a resistor, and inductor properties do not apply.

How can you determine resistance of inductor in single phase with DC source?
Your question is confusing -is the inductor supplied with a.c. or d.c.?In either case, you can determine the inductance of an inductor by disconnecting it, and measuring its resistance with an ohmmeter. If you want a really accurate value of resistance, you could use a Wheatstone Bridge, instead.

Will an inductor work on DC?
An inductor cannot work in dc because the frequency is zero there by making the inductive reactance zero as a consequenceAnswerOf course an inductor can work in a d.c. circuit!
When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
How can convert pulse setting DC to continus DC?
We can use an inductor in series with the circuit to minimize pulses or ripples in the D.C. The inductor provide zero impedance for a D.C source, but provide high impedance for a pulsated wave, so it will not allow pulses to pass through it. A high inductance in the circuit provides smooth D.C. On the other hand we can have a capacitor in parallel to the output.
What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
Can we use inductor in DC circuit?
Yes, but only in a transient manner. Inductors do their "magic" in AC circuits, presenting an inductive reactance that appears as resistance. In a DC circuit, an inductor will simply ramp up current until one of the circuit limits is exceeded, at which point either nothing further will take place, or something will get damaged.In the worst case, of an ideal inductor with an ideal power source, with ideal conductors, the current will linearly ramp up to infinity.Don't misunderstand. We do use inductors in DC circuits. The most common use is as a relay or solenoid, or a DC motor, but there is also resistance or time limits involved which places a limit on the steady state current.
Why doesnt a field coil in a DC shunt motor lead to short ciruit when it is a fact that an INDUCTOR is a short circuit to DC?
Yes, an inductor is a short circuit to dc...that's true....IF the inductor is an ideal one, that is, the inductor has no resistance but has inductance only. Anything in real world, as you know, is not ideal. An inductor is usually made of a copper wire. A copper wire has its own resistance. If an inductor coil is thin and long (i.e. many turns), it will provide an appreciable resistance to DC, and will no longer be a short circuit.
Is it possible to heat coil using dc power supply?
