The resulting maximum current is limited by the resistance of the inductor. As the current increases from zero to that maximum value, its expanding magnetic field induces a voltage into the inductor which opposes the rise in that current. So, instead of reaching its maximum value instantaneously, it takes some time -determined by the equation:
time to maximum current = 5 L / R (seconds)
where L = inductance of inductor in henrys, and R = resistance of inductor in ohms.
What else can I help you with?
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.
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 if an ac supply is given to dc generator?
AC supplies are not given to DC gennies. A DC gen requires a mechanical prime mover.
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 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 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.
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.

What happens when an ac motor is given dc supply?
it burns thats it

AC supplies are not given to DC gennies. A DC gen requires a mechanical prime mover.
What happens if a dc supply is given to a transformer under no load?
when dc supply is given to transformer at primary winding , the output at secondary winding will be zero.Because to induce voltage ,countnie changing flux is required ,that can not be obtained from dc supply...........

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.
