What is inductor and its function?
What is inductor and its function?
An inductor has the functions of developing electromotive force in the direction that reduces fluctuation when a fluctuating current flows and storing electric energy as magnetic energy.
Which component we use as a variable inductor?
Probably the most common type of variable inductor today is one with a moveable ferrite magnetic core, which can be slid or screwed in or out of the coil. Moving the core farther into the coil increases the permeability, increasing the magnetic field and the inductance.
How does an RL circuit work?
A LR Series Circuit consists basically of an inductor of inductance, L connected in series with a resistor of resistance, R. The resistance “R” is the DC resistive value of the wire turns or loops that goes into making up the inductors coil.
What is the variable for inductance?
| Inductance | |
|---|---|
| Common symbols | L |
| SI unit | henry (H) |
| In SI base units | kg⋅m2⋅s−2⋅A−2 |
| Derivations from other quantities | L = V / ( I / t ) L = Φ / I |
What is the working principle of inductor?
An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a magnetic field in the clockwise direction.
What are the application of inductor?
In what applications are inductors used? Inductors are primarily used in electrical power and electronic devices for these major purposes: Choking, blocking, attenuating, or filtering/smoothing high frequency noise in electrical circuits. Storing and transferring energy in power converters (dc-dc or ac-dc)
Why inductor is not used in DC?
The inductor is a passive circuit. It will act as a short circuit when direct current is applied across the inductor. When DC is used in an inductor there will be no change in magnetic flux since DC does not have zero frequency. Therefore, the inductor acts as a short circuit in DC.
What are the types of inductor?
Basic Electronics – Types of Inductors
- Air-core Inductor. The commonly seen inductor, with a simple winding is this air-Core Inductor.
- Iron-Core Inductor. These Inductors have Ferromagnetic materials, such as ferrite or iron, as the core material.
- Toroidal Inductors.
- Laminated Core Inductors.
- Powdered Iron Core Inductors.
What is the function of RL?
RL Circuit refers to a circuit having combination of resistance(s) and inductor(s). They are commonly used in chokes of luminescent tubes. In an A.C. circuit, inductors helps in reducing voltage, without the loss of energy.
Why the current does not rise immediately?
Since the induced emf in an inductor is opposite to the rate of change of current, if the rate is higher the inductor tries to block the rate by inducing the opposite emf. Hence the induced emf is the reason for the slower rise of current.
What are inductor properties?
An inductor is a passive component that is used in most power electronic circuits to store energy in the form of magnetic energy when electricity is applied to it. One of the key properties of an inductor is that it impedes or opposes any change in the amount of current flowing through it.
What is the principle of inductor?
What is the function of an inductor in a circuit?
Inductors are a key electronic component that consist of a coil of wire wrapped around a central core. The electric current flowing through the coil induces a magnetic field around the inductor, storing the electric energy as magnetic energy and creating a voltage across it.
Are there different types of inductors for different applications?
Inductor types based on core 1 Air Core Inductor. 2 Iron Core Inductor. 3 Ferrite Core Inductor. 4 Iron Powder Inductor. 5 Laminated Core Inductor. 6 Bobbin based inductor. 7 Toroidal Inductor. 8 Multi-layer Ceramic Inductors. 9 Film Inductor. 10 Variable Inductor. 更多结果…
How are variable ferrite core inductors used in radio?
When we consider a ferrite core inductor , by moving its core inside and outside on which the coil is wounded , variable ferrite core inductor can be formed. These type of inductors are used in radio and high frequency applications where the tuning is required.
What makes an inductor bigger than a core?
For example, an inductor that has an iron core (whose magnetic permeability is 600) will have a lot larger inductance than an inductor that has a core of air (whose magnetic permeability is 1). These physical properties of an inductor allow it to store a voltage across the inductor and also resist sudden changes in the current.
