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 else can I help you with?
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.
Can we use a DC source with an inductor?
Yes, an inductor allows DC to pass through it. An inductor resists a change in current, proportional to inductance and voltage. At equilibirum, an ideal inductor has zero impedance. The differential equation for an inductor is di/dt = v / l
What happens if dc supply is connected to incomer of transformer?
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
How dc supply is applied to field coil in a brush less alternator?
Through a coupled inductor, similar to a transformer, but working on DC instead of AC.
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.
What will happen if inductor connected with DC supply?
i think in case of dc supply there will not be any induction
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.

Why there is no reactive power in DC system?
In case of dc there is no reactive components and current drawn from the supply is in phase with the voltage.due to absence of inductor and capacitor the reactive power demand in dc is zero.
What happens if dc supply is given to the tranformer?
Transformers depend on fluctuating magnetic fields in order to operate. The operating principle of an inductor, of which a transformer is an example, is to resist a change in current by back EMF which bucks the change (up or down) in current. If you place DC across an inductor, the current would linearly increase until the resistive limit is reached, the power supply's capacity is reached, and/or the inductor self destructs from overcurrent.
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 .
What is the bahaviorS of the INDUCTOR in ac supply?
Because of Ac supply, current lags voltage by 90 in Inductor.
