What happens when dc supply is given to inductor?
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 is an inductor and its current rating?
An inductor is an electrical component, usually a coil, designed to offer a specific value of inductance (measured in henrys). As the operating current of an inductor affects its inductance its inductance value (inductors are not linear devices, due to their hysteresis characteristics) is normally expressed for a specific range of operating currents.
What happens to a light bulb when put in series with a inductor?
When you put a light bulb in series with a inductor, the inductive reactance of the inductor reduces the current available to the light bulb, making it less bright. For this effect to be noticed, however, you need a very large inductor. To cut the current in a 60W bulb at 120VAC/60Hz by one half, for instance, you need an inductor around 0.6 henrys.
Effect of q factor on maxwell inductance bridge?
the bridge is preferably balanced by capacitor parallel attached resistance value. so, q factor of the inductor is given by w L / C at balance condition. q-value is low prefer
The resistance that an inductor poses to the flow of ac?
An inductor has two properties. The first is resistance(measured in ohms), which is due to the length, cross-sectional area, and resistivity of the conductor from which it is wound. The second is inductance (measured in henrys), which is due to the length of the inductor, its cross-sectional area, the number of turns, and the permeability of its core.The inductor's resistance limits the value of current flowing through the inductor. The inductor's inductance opposes any change in current.
Is there no induced voltage in an inductor unless the current is changing?
In an ideal inductor, no, there is no voltage induced across an inductor unless the current in the inductor is changing. However, since there are no ideal inductors nor power supplies, eventually an inductor will draw a constant current, i.e. the limit of the power supply; and, since no inductor has zero ohms at equilibrium, that current will translate to voltage.
What is significance of imaginary part in inductor?
No inductor is perfect and has a capacitive and resistive component. As frequency increases, these components have more effect on the circuit operation. A capacitive component would be out of phase and be the imaginary value.
What is the effect of changig length or mass of pendulum on value of g?
Changing the length will increase its period. Changing the mass will have no effect.
What is working principle of inductor?
A changing current through an inductor induces a voltage into the inductor, the direction of which always opposes the change in that current.So, in a d.c. circuit, an inductor will oppose (not prevent) any rise or fall in current, although the magnitude of that current will be determined by the resistance of that inductor, not by its inductance.In an a.c. circuit, because the current is continuously changing both in magnitude and in direction, it acts to continuously oppose the current due to its inductive reactance. Inductive reactance is proportional to the inductance of the inductor and the frequency of the supply. The vector sum of the inductive reactance of the inductor and the resistance of the inductor, is termed the impedance of the inductor. Inductive reactance, resistance, and impedance are each measured in ohms.
What is effect of changing mass of pendulum on value of 'g'?
yes it can change....
What is the Value of currie temperature?
Each inductor has its own currie temperature. You have to check the datasheet for the specific inductor in use.
What is the effect of inductor you rectifier?
it makes current wave more smooth

Are inductors measured in ohm's Henry's or reactance?
Inductors can be measured in all three of the above:When an the value of an inductor is given in henrys you are being given its "capacity" to store energy in a magnetic field.Because the inductor is not made of a perfect conductor (one without resistance) it will inevitably has some associated resistance. This is the value that is being referred to if the value of ohms is given.If an inductor is part of an AC (alternating current) circuit it will have a changing "resistance" (resistance as seen by the source) that is directly related to the frequency of the circuit. This is where the reactance value would be given. It equation is given as: 2*pi*f*L. Where f is frequency in hertz and L is the inductance given in henrys..

What is the reactance value when inductor was saturate?
A: when a coil is saturated there is only resistance of copper
