What is the function of inductor in computer?

Inductors are used as the energy storage device in many switched-mode power supplies to produce DC current. The inductor supplies energy to the circuit to keep current flowing during the “off” switching periods and enables topographies where the output voltage is higher than the input voltage.

Why would you need an inductor?

Inductors are typically used as energy storage devices in switched-mode power devices to produce DC current. The inductor, which stores energy, supplies energy to the circuit to maintain current flow during “off” switching periods, thus enabling topographies where output voltage exceeds input voltage.

Why are inductors used in AC circuits?

An Inductor is usually a coil of wire that sets up an alternating magnetic field around it when an alternating current flows through it . Inductance is the property of an inductor that opposes the change in current.

What are the characteristics of inductors and its applications?

Inductors have the following basic characteristics. Current flows to generate a magnetic field, and a change of the magnetic field generates an opposing current. Changes electrical energy to magnetic energy and stores it. DC can pass through but AC cannot easily pass through at higher frequencies.

How do inductors store energy?

Inductor stores the kinetic energy of moving electrons in the form of a magnetic field. Energy storage in an inductor is a function of the amount of current through it. The more the current , the more the magnetic field and the more energy is stored. An inductor tend to resist change in current.

What is real inductor?

A real inductor has both an inductance and a resistance. We draw a real inductor as an ideal inductor connected in series to an ideal resistor in a circuit diagram.

What are the applications of an inductor?

Applications of Inductor. Like resistors and capacitors, inductors are also passive elements which are used to store the electric energy in the form of magnetic field. Simply an inductor is a wire or coil of a good electric conducting material with few turns (twists) in it.

Why does an inductor block the flow of current?

The reason for this strange behavior is the inductor. When current first starts flowing in the coil, the coil wants to build up a magnetic field. While the field is building, the coil inhibits the flow of current.

How do you determine the capacity of an inductor?

The capacity of an inductor is controlled by four factors: The number of coils – More coils means more inductance. The cross-sectional area of the coil – More area means more inductance. The length of the coil – A short coil means narrower (or overlapping) coils, which means more inductance.

What is indinductance and how does it work?

Inductance is the main principle behind it in which the magnetic field in the coil will oppose the flow of electric current. The proximity sensors mechanism is used in traffic lights to detect traffic density.
