What is the power consumption of a capacitor or inductor?
Capacitors and Inductors theoretically consume no power. In real life, they only consume power because they have an internal resistance.
Is the resistance of the inductor is zero?
The power consumed by an inductor is not zero since it's resistance is not zero either. The power consumed is just too minimal that it can be ignored. What the inductor does is, during one half of the Current's sinusoidal waveform, it stores energy in the form of magnetic flux. During the next half,it discharges the stored energy into the circuit by losing the magnetic field. Hence,they say it doesn't consume power. If the inductor's resistance was significant then you will see that it will consume power. Resistance and Reactive resistance are two different things.
How much power is consumed by a pure inductor of 1henry connected to 200v supply?
The current through a pure, or ideal, inductor having zero resistance, would lag the voltage with a phase angle of 90 degrees. The inductive reactance of a 1 Henry inductor at 60 hz is about 380 ohms. XL = 2 * pi * f * L so 200 volts at 380 ohms is about 0.53 amps and the power drawn, using the basic Power equation: power = volts * amps, would be about 105 vars. Var is the correct term for volts times amps, or volt-amp-reactive, where we consider the phase angle to be 90 degrees.
Is it possible for an energized circuit at 240 volts and 100 amps but no power?
Yes if you are referring to no real power, no if you are saying no power (real or reactive). You could have 100A flow from a capacitor bank or inductor bank, which should consume no real power, but provide voltage support / pull down when on line by introducing reactive power to the system.
Why inductor is used in electrical circuit?
To improve the power factor
Does Inductor consume any power in electric circuit?
If it's a pure inductor, no power consumption. However it must be wound using unobtanium wire which has zero resistance, and the core must be vacuum. Air is nearly lossless.

Why no power loss in pure inductance?
An inductor is a device which stores energy as a magnetic energy.... Ideal inductor have no resistance.....so there is no power loss.... power loss = (I*I)*R
Is pure inductor consumes energy?
Pure inductors consume and produce power, just like other reactive devices. The difference is that the current is not in phase with the voltage, resulting in the waveform of the power being oscillating about zero, with a net mean power of zero. In this "pure" case, the power factor is zero, but that does not mean there is no power - its just that the power "reading" is unsophisticated and not compensating for power factor.
What is the value of power factor for a pure inductor?
Angle between v and i is 90 deg so, cos 90 = 0 Same for pure capacitor
Is the resistance of the inductor is zero?
The power consumed by an inductor is not zero since it's resistance is not zero either. The power consumed is just too minimal that it can be ignored.

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.

Is there any power consumed in pure inductor and pure capacitor?
In an AC circuit energy flows into an inductor in one quarter-cycle and flows out on the next. Ditto for a capacitor. Therefore over a cycle, no net power or energy is consumed in a pure capacitor or inductor.Another Answer'Power' is the rate at which energy is transferred. In the case of 'pure' inductance or capacitance, energy flows from the supply to the device during the first quarter-cycle of current, where it is temporarily stored within the magnetic (inductors) or electric (capacitors) field, only to be returned to the supply during the following quarter-cycle. You could describe this action as 'energy sloshing back and forth between the supply and the device'. The rate at which this energy transfer takes place is called 'reactive power' and is expressed in 'reactive volt amperes'. None of this energy is lost or, to use your expression, 'consumed'.'True power', expressed in watts, is the rate at which energy is expended -i.e. energy taken from the supply and then dispersed through work (e.g. by motors) or heat transfer (losses). This does NOT occur in purely-inductive or in purely-capacitive loads. So, in answer to your question, 'power' (in the sense of 'true power') is NOT 'consumed' by a pure inductor or capacitor (remember, technically, it's energy that gets consumed, not power -power is simply a rate).You should bear in mind, however, that there is no such thing as a 'pure inductor' or 'pure capacitor' as each will exhibit some degree of resistance. Resistance results in the expenditure of energy, the rate at which it occurs being 'true power'. So 'real' inductors and capacitors combine 'reactive power' with 'true power', the vector-sum of which we call 'apparent power', expressed in volt amperes.
