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.
What else can I help you with?
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
Which filter is practically preferred to get pure DC output?
pi filter is best using inductor and capacitor.
What is the value of power factor for a pure capacitor?
0. Power factor has to do with the amount of real power. if you have a purely capacitive load, there is no real power flow, thus pf = 0. For purely resistive load, power factor will be 1.0.
What is meaning of RLC?
RLC circuit(or LCR circuitorCRL circuitorRCL circuit) is anelectrical circuitconsisting of aresistor, aninductor, and acapacitor, connected in series or in parallel. The RLC part of the name is due to those letters being the usual electrical symbols forresistance,inductanceandcapacitancerespectively. The circuit forms aharmonic oscillatorfor current and willresonatein a similar way as anLC circuitwill. The main difference that the presence of the resistor makes is that any oscillation induced in the circuit will die away over time if it is not kept going by a source. This effect of the resistor is calleddamping. The presence of the resistance also reduces the peak resonant frequency somewhat. Some resistance is unavoidable in real circuits, even if a resistor is not specifically included as a component. A pure LC circuit is an ideal which really only exists in theory
Power factor for pure resistive circuit?
ratio between true power and apparent power is called the power factor for a circuit Power factor =true power/apparent power also we conclude PF=power dissipated / actual power in pure resistive circuit if total resistance is made zero power factor will be zero

What is the var meter?
A VAR Meter is used to measure Reactive Power in AC Circuits - Pure reactive components dissipate zero power, which makes sense in a DC circuit, as a capacitor passes no DC current and an inductor displaces no voltage. Yet, in an AC circuit, the reactive components "seem" to dissipate power, as current passes through the capacitor and the inductor sees a voltage drop. This counterfeit power is called "reactive power" and is measured not in Watts, but in VARs (Volt-Amps-Reactive). Its mathematical formula symbol is "Q".

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
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.
What is the active power consumed by pure inductive reactance?
The active power of an inductor is zero. As we know, the active power is the result of product of supply voltage and in-phase component of load current. But the load current in pure inductive load lags supply voltage by 90 degrees. So there is no component of load current that is in-phase with the supply voltage. Therefore, the active power in inductive reactance is zero.
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 a pure inductor do not consume power?
whose resistance is zero.but it is practically not possible. there is something resistance present in the wire
What type of function of capacitor in dc power supply?
It filters ac to pure dc
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 capacitor?
0. Power factor has to do with the amount of real power. if you have a purely capacitive load, there is no real power flow, thus pf = 0. For purely resistive load, power factor will be 1.0.
What is a pure capacitor?
A pure capacitor is an idealized version of a capacitor that has only capacitive reactance and no resistance or inductance. It stores and releases electrical energy in the form of an electric field. Pure capacitors are often used in electronic circuits for filtering, smoothing, timing, and energy storage purposes.
