What is an inductor and what does it do?
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 is an inductor Class 12?
An inductor is an electronic component that is usually made up of an insulated wire wound up into a coil. This is a component that adds inductance to the circuit. The ratio of magnetic flux to current is defined as inductance. It can be used to determine the amount of magnetic energy that can be stored in an inductor.
What is inductor short answer?
An inductor is a coil consists of an insulated wire wound over an air or iron core with a fixed number of turns. It stores energy in the magnetic field when current flows through the coil. It has a property to opposes any change in the amount of current flow through the coil called inductance.
Where is inductor used?
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.
What is inductor and its types?
The inductors are classified into two types. 1. Air Cored Inductor (wound on non-ferrite material) – The inductor in which either the core is completely absent or ceramic material is used for making the core such type of inductor is known as the air-cored inductor. The ceramic material has no magnetic properties.
Why are inductors made of copper?
The inductance coils made of copper will have very small ohmic resistance. Due to change in magnetic flux a large induced current will be produced in such an inductance, which will offer appreciable opposition to the flow of current.
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 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.
Do inductors lead or lag?
Pure inductive circuit: Inductor current lags inductor voltage by 90°. Looking at the graph, the voltage wave seems to have a “head start” on the current wave; the voltage “leads” the current and the current “lags” behind the voltage. Current lags voltage by 90° in a pure inductive circuit.
What is another name for inductor?
Also called inductance. Electricity. a coil used to introduce inductance into an electric circuit.
Does an inductor store energy?
Inductors Store Energy. The magnetic field that surrounds an inductor stores energy as current flows through the field. An alternating current (AC) flowing through the inductor results in the constant storing and delivering of energy.
What is called capacitor?
Capacitor, device for storing electrical energy, consisting of two conductors in close proximity and insulated from each other. A simple example of such a storage device is the parallel-plate capacitor.
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 is the symbol for inductor?
Inductance only has an effect when the current is changing as in an AC circuit. Inductance is measured in Henrys. The symbol for inductance is a series of coils as shown below. The letter “L” is used in equations.
