In other words, an unpowered inductor cannot sustain its magnetic field.Where E is the energy in Joules, L is the inductance in Henries and I is the current in amps.If you have an inductor of 20uH with a 5A current flowing through it, then the energy stored will be 0.00025J. Thus, the EMF oppose the change of current that changes the magnetic field. Along with a capacitor, it acts to prevent sudden changes in the power supply output voltage and current.RF circuits make use of an interesting LC circuit called a tank. Or we can say that the inductor is an electrical device which possesses the inductance. It consists of a conductor such as a wire, usually wound into a coil. It suggests that the magnetic field inside the inductor can be manipulated.

How can improve the quality of power to 0.98 pf?

The capacitor is charged and discharged into the inductor, which builds up its magnetic field. The permeability of the inductor remains same due to the ceramic material.In air core-inductor, the only work of the core is to give the coil a particular shape. They are usually used for low frequency line filtering, since they can be rather beefy and have large inductances. At higher frequencies, the impedance of the inductor increases steadily, so the signal can pass through to the output, hence it is called a high pass filter.In the second case, the inductor allows DC and low frequencies to pass through but blocks all high frequencies from the output and so it is called a low pass filter.Inductors, since they are made of copper wire and ferrite, tend to be expensive and find most of their uses in radios, power supplies and telecoms equipment.In power supplies, the property of an inductor to prevent sudden changes in current is used. An inductor consists of a coil of conducting wire. It’s incredibly easy to make one — just make some loops with a wire. An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. This changing current (AC) produces a changing magnetic field that induces a voltage, and it oppose the current that is generated from the magnetic field. a coefficient of how easily the magnetic field can be created in a given medium, n is the number of turns, a is the area of the coil and l is the length of the coil.Again, the Henry is a very large unit, so practically inductors are measured in microHenrys, uH, which is a millionth of a Henry, or milliHenrys, mH, which is a thousandth of a Henry. This powder is mixed with an epoxy resin and molded to form cores around which wires can be wound.Inductors connected in series and parallel behave the exact opposite way to capacitors.For example, to calculate the inductance of a group of inductors in series, you can simply sum up the values of the individual inductances.Where L is the total inductance and L1, L2…Ln are the individual inductances.Suppose you have two inductors, one measuring 10uH and the other 15uH, then by putting them in series you obtain a total inductance of 25uH.Inductors in parallel behave the same way as resistors in parallel, the inductance is given by:In this way if you connect two 10uH inductors in parallel, you’ll end up with an inductance of 5uH.Inductors can store energy much like capacitors, but the energy is gone the moment you disconnect the power and the magnetic field collapses.

It consists of a wire, generally twisted into a coil. The air cored structure has many advantages like they reduce the core losses and increases the quality factor. The current which reduces because of the inductance is known as the inductive reactance. With this, it can also store energy in the magnetic field when the current passes through it.

Occasionally you might even find very small inductances measured in nanoHenrys, which are a thousandth of a uH.Now the µ in the above equation has some interesting implications. The core provides the low reluctance path to the magnetic flux.The magnetic field induces the EMF in the coil which causes the current.
