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.

The only device that develops true power in an electronic circuit is the inductor?
The resistor is the only component to develop true power in an ac circuit. The inductor and capacitors absorb energy on one half cycle and return it to the supply on the next. The resistive part of the inductor (wire coil if low frequency type) will develop true power due to its value of resistance ie it will get warm.
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".

How does a inductor or capacitor returns power to circuit?
A: Current flow only if there is a return path to the source it does not matter what it is connected to. What leaves at one end of the source will be identical to the return in current
Can we use inductor in DC circuit?
Yes, but only in a transient manner. Inductors do their "magic" in AC circuits, presenting an inductive reactance that appears as resistance. In a DC circuit, an inductor will simply ramp up current until one of the circuit limits is exceeded, at which point either nothing further will take place, or something will get damaged.In the worst case, of an ideal inductor with an ideal power source, with ideal conductors, the current will linearly ramp up to infinity.Don't misunderstand. We do use inductors in DC circuits. The most common use is as a relay or solenoid, or a DC motor, but there is also resistance or time limits involved which places a limit on the steady state current.
120 volts equal how many watts?
It depends upon how much amperage is utilized in a circuit. A circuit with 2 amps of current and 120 volts would consume 240 watts of power. The same circuit with 4 amps would produce 480 watts. You have to have 2 values of Ohm's law to figure out the third. See "Ohm's law" on the internet for more information on how circuit values are determined.
What is the role of reactive power in an electric circuit?
Some electrical machines work on the principle of electromagnetic induction. For such events to occur, we need inductor due to which reactive power flows in the circuit. Since, this power is due to the energy storing elements in the circuit like inductor and capacitor. That is why, we need reactive power in a electric circuit.
Why inductor is used in electrical circuit?
To improve the power factor
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.
What happens when you stick a core into a coil inductor in an undriven circuit?
If the circuit is undriven, there is no power, so inserting a core does nothing. In general, however, inserting a core into an inductor increases its inductance. Depending on the circuit, that lowers the resonant frequency.
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

How can you make the electric circuit?
Anything with a voltage power source, connecting wire and a load is an electric circuit. Hence if you have a flashlight you have an electric circuit.
Which term does not represent electric power in a circuit?
There are many terms that do not represent electric power in a circuit, such as cauliflower, aeroplane and rabbit.Electric power in a circuit is measured in watts (W).
In an AC circuit with only an inductor what will an increase in frequency do?
Inductor impedance is given by jwL, where w=2*pi*frequency. Therefore as the frequency increases the impedance of the inductor increases, causing a larger current flow and a larger power dissipation across the inductor
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.
Where an electric circuit begins?
power source
